Yandere is a Japanese word for someone who has an unhealthy romantic obsession. This is often used as an archetype in Japanese fiction, where one can be the sweet, romantic, loving, affectionate character type as well as the obsessive, dramatic, violent type. While a yandere generally shows affection through obsessive acts and becomes violent or creepy when he/she is jealous or ignored, by imitating the yandere type in a sarcastic way, you can make this strange behavior humorous. Act like a yandere by conveying your mood through facial expressions and controlling your yandere smile. Then all you have to do is dress in yandere clothes, and you'll be hilarious yandere.
Steps
Method 1 of 3: Making a parody on a yandere

Step 1. Choose a target that has no problem with your advances
The target of your yandere love should be someone you find immediately impressive. The kind of person you could really dedicate yourself to. Common targets include sports team captains, people who have just moved to your area, and emerging leaders (see the animé Code Geass).
- Your target must come across as the key player in his or her own life adventure. In a manner of speaking, he or she should be the hero of his or her own story…..and yours too.
- Your target's talents and skills should be something you respect or admire. In this way, your admiration for these talents and skills will be genuinely intense.
- Choose someone who can withstand your excessive advances. It should not make the other person uncomfortable. Pick someone who likes weird games and knows you well.

Step 2. Be the target's biggest fan
Attend the target's matches, practices and rehearsals. Be a one-person supporters club. Give your loved one a bottle of water whenever he or she comes off the field or off the stage. Let the other know how committed you are.
Talk to friends and classmates about the target's creative pieces or virtuoso piano performances

Step 3. Protect the target from inappropriate advances
You have devoted yourself wholeheartedly to the target, so it is only fair that the target is reciprocal. Cast your Death Star gaze on anyone trying to squeeze between you and your loved one. Admonish the target of your love not to give others the wrong ideas when it is clear that they are not meant for each other.
Yandere types are often violently jealous when the target of their love is violated by the affection of an outsider. However, this is not acceptable in the real world. You may only 'protect' your target in a playful, fun way

Step 4. Show respect for the target
Let the target choose the places where you can meet, which movies you will see together, and the snack bars where you will eat in your spare time. Do what your target asks of you. Show respect for your victim's wishes and goals.
The target will perceive your easy and pleasant ways as harmonizing with their own. This will pull the other person deeper into the complex web of your love, from which he or she will never, ever escape

Step 5. Express your cute aggression within reasonable limits
Cute aggression is when you think something is so cute or you love something so much that you want to harm it, like "thinking something so cute you want to squeeze it!" It's only natural that seeing the target of your love makes you feel a little playful.
- Give the target a firm hug, a gentle and gentle tap on the arm, or a punch to the shoulder. Squeeze your eyes slightly when you do that and make a cute noise. Let them know that you think they are so cute that they are stronger than you.
- Throw light, safe items at your target, such as gloves, scarves, and paper. Shout out for joy when you do, and say something like, "You're so cute, I can't bear it!
Method 2 of 3: Dress your yandere

Step 1. Create an aura of innocence around you
Women should dress in conservative skirts and dresses. Men should prioritize a clean look, wearing things like khakis, plain shirts, shirts and school uniforms. Keep your style simple. Yandere is something you feel in the heart, while it looks normal from the outside.
Keep your hairstyle simple. Avoid flashy or sharp haircuts. A yandere is quite modest, apart from the erratic, fleeting love he or she has for the love victim

Step 2. Add fun accessories
Women can put ribbons in their hair, like around a ponytail. Guys should consider wearing glasses. You can wear fake glasses if you otherwise have perfect vision.
A simple watch, necklace or bracelet can keep your yandere outfit together. Avoid too much over the top or flashy accessories. The dignity of your love must conquer the heart of your victim… or else

Step 3. Wear softening colors
Green, blue and violet have a natural calming effect that you can use to your advantage. Though the fire of the yandere burns scorching in your heart, the colors of your wardrobe will say, "Choose me--I'm very normal!"
Earth tones, such as brown and green, can also give the impression of stability and have a calming effect
Method 3 of 3: Sending Yandere signals

Step 1. Activate your beast mode
Yandere characters usually have a special way of looking that they use to indicate when they are on the warpath. Often this is a somewhat eerie expression, which is animated by a shadow cast over the face. When people meddle with you and your target, you stare at them through your eyelashes to mimic this.
- When someone is the target of a yandere person's love, another common reaction is to open their eyes wide with an expression that could be described as "threateningly shocked."
- Pulling an eye or the corner of your mouth can be that showing that you are slowly going insane. If you feel that your inner beast is moving, express your feelings to the rest of the world through a vibration.
- Don't do this to people around who aren't aware of the joke, as it may scare them.

Step 2. Get your moods across with clear facial expressions
Be expressive with your face. Clearly show the target of your love how you feel with a smile, longing and beautiful looks. If things start to move romantically or if someone squeezes in between you and your target, let your facial expression clearly reflect your disapproval.
While expressiveness is a common feature in yandere, it may be due to the fact that Japanese animation and manga, which are often highly expressive, are the most common media in which the yandere archetype appears

Step #3. Manage your yandere smile
Use your phone or a sound recorder to make a sound clip of your smile. Listen to it. Your smile should be cute, but with an underlying edge. Adjust your smile little by little using the sound recorder to check the changes you've made. Do this until your yandere smile has become second nature.
Changing a natural reflex, such as laughing, can be difficult. It may take a while and some trial and error to change your smile by yandere standards
Tips
- While a true "yandere" person would be scary in real life, you can jokingly pretend to be yandere around other people who like to go crazy.
- Pay close attention to whether others start to feel uncomfortable. You should only act like a yandere with people who are okay with it. If someone seems uncomfortable with it, stop and explain that you weren't serious and apologize for crossing his or her boundaries.
- Make sure you only do this around people who know you're just playing and like it. You don't want to scare someone and make them think you're really like that.
- Don't brag about being a yandere! A real yandere will never admit this!
- Only act like a yandere around people who really understand what you are doing.
- Don't go too far with the yandere act! You don't want anyone to think there is something wrong with you.
Warnings
- Actual mental illness is no joke and should be taken seriously. If you really feel obsessively or dangerously connected to another person, see a mental health professional.
- Doing like a yandere should only be done to have fun with this archetype or to imitate your favorite characters.
- Make sure the people around you know what you're doing. This cannot be emphasized enough. Being protective of someone you love is fine, but suddenly developing stalking behavior and scaring people is not okay. Make sure people know it's a joke.
