Have you been walked all over you, have you been ridiculed without anyone standing up for you, or have you taken a hard time because of the fault of others? Well, then it's time for you to act and learn how to be nice and mean too. Keep in mind that there's nothing nice about mean people, and you won't be liked by others if you're just rude and unkind to them all the time, so don't be too crazy.
Steps
Part 1 of 2: Being a bitch like Regina George

Step 1. Get the right look
Regina, from the American film Mean Girls, has power. One of the reasons others give her that power without a fight is that she's pretty and always, always, always looks good. Sadly but true, the world looks at you and labels you based on the outside they see. So if you want to have enough power to be bad, you'll have to get the right look to start with. And what impresses girls? Right, pretty girls.
- Be fashionable. That can mean that you follow the latest trends, but also that you are a trendsetter yourself. Choose your outfits as carefully as possible and make sure the clothes you wear fit you well. Stick to a certain style to create an identity for yourself.
- Always carry a small bag with you. Make sure you always have some make up in that bag. Regina George looks immaculate even during gym class. She is successful because she has everything under control down to the last detail. The lip gloss, the accessories – she is always ready for anything.

Step 2. Be extremely nice.
.. to certain people.
If you act mean to everyone, you'll just be a horrible witch who, for understandable reasons, isn't liked by anyone. You have to act like it's really hard to get your approval – there are only a few people who deserve to be praised by you, yes, by you, that little picky bitch. If people notice that they don't meet your standards, they will try harder for it.
Be openly nice to a few people. Others need to see that you can be really nice and nice to people, if they deserve it. Choose those you are nice to carefully and be consistent. These people will become your best friends

Step 3. Grab what you want
Another might really want something, but you just take it. Why not? Someone will get it and why shouldn't it be you. If it's a boy, great. When it comes to a smart classmate's homework, even better.
If people don't offer you the things, ask for them. Create opportunities to make them feel close to you. Ask a girl for the nail polish she is just showing off. She will love that you want her look. If you forgot your lunch break money, tell a nice guy – he'll be more than happy to come to your rescue and rescue you. It's all about taking advantage of the little moments

Step 4. Bite off you
Regina always has an insulting comment ready that is quite biting and that she can hurt someone with, without being too thick on it. If someone makes your life miserable, do the same to them. Just do it subtly - the point is to make the other person wonder if you really meant what you just said.
If someone tells you you're being mean, just say, 'I'm not being mean – I'm just standing up for myself. There's nothing wrong with that at all. You should just try it once in a while – I bet you're getting tired of being walked all over you by now. And besides, nobody likes people who are walked all over them.' Cover your insults to mislead people. Or you just say straight up, 'Blow it up, Allison. Did you know that nobody likes that tangled new haircut of yours?' Then you throw your hair over your shoulder and walk away

Step 5. Flirt
As far as boys are concerned, you should try to appear a little more sophisticated. You still have to expect (and take for yourself) things, but you have to do it elegantly and with a smile. They're supposed to feel flattered by your attention, so be careful with it. Anyway, which guy is good enough for you to start with? Remember, guys (and people in general) are ultimately in the world just to be used and manipulated by you!
Smile. A mean person never smiles, right? Make sure you look happy and talk to the guys - they won't notice your meanness at first because they won't get to see that side of you directly

Step 6. First pretend to be nice and nice
Remember how Regina George first stopped that girl in the hall in the vintage skirt to tell the girl she loved that skirt? And then she turned around and made a sound of disgust? Precisely. Like this. So. The vintage girl has run away thinking she belongs to the top and Regina is super nice. Now Regina has all the power. Power. Check. Manipulation.
-
Let's assume you do the exact same thing. Suddenly the vintage girl comes up to you and asks if you want to walk to the gym with her, because she knows you are in the same class. You might say, 'Are you sure they're in the same class? I've never seen you there. But I'm sorry, I've already made an appointment with Geertje.'
Those magic words "I'm sorry" will keep the vintage girl from attacking you for your action, even if you're probably really offended just for having the courage to even talk to you! Also, you phrased your insult as a question. It may seem nicer, but there's nothing nice about it if you don't mean it

Step 7. Fool the adults
If you go crazy with your meanness, you'll soon have all the grown-ups against you. When authority and you cannot get through the same door, you will have problems. So don't let the adults see this side of you.
Make sure you are a good student. If you're a good student who behaves in an exemplary way, it's hard for teachers to figure out what a bitch you are. And if you're nice to them, you'll only make it harder for them

Step 8. Expect the world
When you have high expectations of people, sometimes they crave to live up to those expectations. So if people don't comply, let them know. The idea behind this is that no one should want to disappoint you – in fact, they should want more than simply meeting your expectations, imperfectly and without a fuss.
Imagine that for Dutch you have to work on a project with some girls with whom you are not friends. One of them said she would bring poster paper on Monday, but she left it at home. Whether you can drop by her after school to finish the project. No, you can't. You have other plans. She should have remembered – as a result, your whole group is falling behind. She will have to work on it herself tonight and then meet with you tomorrow

Step 9. Never take the blame yourself
To be bad in a balanced way, you have to make sure that your other side is a holy angel. This is the girl who never does anything wrong – and if she does, she has a good reason for it. Never put on the penitent for anything; always have an excuse or a black sheep to blame.
So, Karin heard that you told Geertje that she started to get a big ass. What? No of course not! That story is completely taken out of context. Geertje told you that Karin was getting so fat. She just couldn't stop talking about it! So to get her to shut up, you said that she might have gotten a slightly fatter ass, but she looked exactly the same about everything else. And secretly you would also like to have a slightly rounder ass. Then you propose to go out with Karin, to make sure that she starts to feel a bit better

Step 10. Be forgetful
Even if you've been talking to someone for 50 minutes, make sure you forget their name right away, or at least pretend. You know that that person is in your math class and you've been in school together for 6 years, but he or she doesn't need to know that you know that.
People are immensely annoyed by this. If it's really starting to annoy them ("Are you serious? You asked me for my homework last week. What's your problem?"), then maybe you can give in. Then brush it off as a moment of forgetfulness that isn't so important. Your nonchalant response will make the other person wonder if his or her response was perhaps a bit exaggerated
Part 2 of 2: Bringing out the bad in yourself

Step 1. Be sure of yourself
You're talented and beautiful, no matter what people think. You may not be perfect, but nobody is. Learn to appear confident, act, look and feel confident. You will be amazed at how much power you can gain just by acting confidently.
Look at it this way: if minors sneak into a movie theater, who get caught? The ones who giggle, look around and move just a little too fast. The kids who keep a cool head, stay calm, and walk in without hesitation, aren't asked anything -- because they look like they belong. Simply put, if you're confident, you'll get away with things more easily

Step 2. Increase your independence
Learn to do things on your own and only ask for help when you're really desperate. You don't need anyone. When you depend on someone, you need them – and that's something you want to avoid.
By being independent and more on your own, you will be more successful in not depending on others and their approval. If you worry less about what others think of you, the world will open up to you and you can do whatever you want

Step 3. Say what you want and say what's on your mind wherever you can
People may not like it, but they will respect your honesty. As long as you speak the truth it will be difficult to argue with you.
Prepare yourself for others to treat you the same way. If you don't have good manners or behave according to normal social norms, others will notice and feel more comfortable attacking you in exactly the same way you attacked them. If you say, "Of course you failed that test because your IQ is lower than average" (which is possibly true), the other person will be immediately offended and probably want to get back at you by saying something ridiculous like: 'I'd rather fail than have a face that only my mother could find beautiful, like yours.' Be prepared for people to be mean to you too

Step 4. Befriend confident, mean girls
They will boost your confidence and the way you stand up for yourself, unlike shy girls who let all the bullying happen. You could use some help, as it will be difficult to maintain your new posture 24 hours a day, seven days a week.
It will be hardest to be consistent with these girls. You want to let them know that they have your approval…but not for long. Because if one of them is going to be mean to you, you'll have to chase her away too. Show yourself your tough side to them, but at the same time make sure they stay on your side. "So he said you were fat? Well, you actually have to lose some weight, but I can actually lose a few pounds. Let's do it together.'

Step 5. Don't be afraid to take on a mean bitch
We all know who they are and how destructive they can be. Never be nice to such a witch - or, better yet, ignore her. Make sure she realizes that you don't like her and that you aren't afraid of her.
You are not meant to be downright mean to her unless you are aware of the consequences your actions could have and have no problem with that. But if you go too far you will sink too deep and she will come out the winner. Just try to ignore her if you can. Being treated with indifference feels worse than hatred – if you hate someone, at least that person is important enough for you to show. On the other hand, if you treat someone with indifference, it means that you really don't care about their existence. And that really hurts

Step 6. Be unpredictable
If you keep switching moods or choices whenever you feel like it, people will be wary of you. They will also find it very tiring, so do it at the right time and in the right places. This means that you have to be really mean and really nice.
Alternate your meanness with nice moments every now and then - you will completely upset people with it and it will be really funny to see their reactions. Stop a girl in the hall and tell her you really loved her book report. Tell someone else that she really did a fantastic job at the volleyball tournament last Thursday. It may seem like just one small comment, but after all your other negative comments, one unexpected, positive comment makes an extra impact

Step 7. Don't be a girly girl
Giggling, always wearing pink and acting like a toddler isn't going to work. Be what you want, but make people aware of the power you have to be mean. You're serious, and you're not just going through puberty.
Being mean only works if you deal with it in a mature way. Being a snitch isn't the same as being mean, that's just stupid; no one will accept that. But if you're mature, assertive, and sincere and don't hang out with stupid people, that's something people have a harder time objecting to. Be smart about your newly discovered aggression
Tips
- Always keep your mask on. Always try to be hard on others, otherwise people will think your "badness" is fake.
- Try befriending more guys. They can be an extra ally for you if you need them.
- Stand up not only for yourself, but also for your friends and girlfriends. They make you respect you for it and start liking you more for it.
- The word "bad" should actually be misleading. What you want is to be strong and assertive. Make sure you know the difference.
Warnings
- Don't confuse 'mean' with 'grumpy'. Smile and laugh out loud and respond positively to others.
- Being bad and mean is not the same as bullying! Make sure you don't treat people badly all the time; just try to exude more confidence. Only stand up for yourself if someone else has hurt you; in such a case be assertive and do not hold back.
- While you will become popular with a lot of people, there will also be people who will strongly disapprove of what you do. Don't try to take advantage of being popular. If you do, you'll just be a bully – not a popular girl!
- Regina George was not a good person. She manipulated people and had no real friends. Prepare to feel very, very lonely.
