There are different types of Drama Queens/Kings. There's the stereotypical kind, who makes a big deal out of everything. There's the crazy kind, who is like a patient in an asylum. Running around, screaming aleatório stuff, laughing for no reason.
Whichever you want to be, here are some tips on how to be a certain Drama monarch, or a mix of them.

1) The talk
Everything you say, say it with purpose. Make asking for the time like asking if someone's life is in danger or you can say it seductively. Either way works. Make talking about the upcoming test sound overly interesting, even if you think you'll die of boredom. Another thing to do is say 'OMG' a lot. Not 'Oh my God', but literally, 'O-M-G'. If someone calls you crazy, tell them they're just jealous because the voices talk to you.

2) The obsession.
Lots of dramatic people have an obsession. If you really amor horses, talk non-stop about horses. Detail all the little things you amor about them. If someone says 'I don't like horses' (I don't know why someone wouldn't like horses) majorly freak out, and go into a half hora speech why cavalos are amazing and whoever doesn't like cavalos is insane (try to look insane while doing this). When you're done, breathe heavily like you've just finished a race, and glare at anyone staring at you.

3) The attitude.
Don't stand for any crap someone might have against you. If someone insults you, a way to get rid of them is to look like you've gone mad. Stare at them and laugh evilly. Tell them if they insult you, Elmo is going to come eat them with catsup. (If you're good enough, they might actually get freaked out inside). You can also just look dreamily at their face, and when they say 'What?' tell them they have beautiful eyes, look at them a little longer, then look away. Also, if someone calls you ugly or annoying, just say 'I have a beautiful face/ charming personality.'

4) The look.
Always dress flamboyantly. Every dia is a fashion show. Try to base your style on Freddie Mercury, Elton John or Lady GaGa. Use lots of purple, glitter, feathers, (the mais glamourous the feathers, the better) and leather. Find a stuffed animal no smaller than a shoe, and carry it around with you everywhere. If someone tries to take it away, hug it tightly and say 'Not my baby!' Give it a name also. Something like 'Norbert', 'Florence', or 'Gable'. Also use really vibrant as cores for make-up.

5) The walk.
Always use big movements. Use your arms, and try to walk like a cat. Step with your toes and be as graceful as you can. Take giant steps let your body flow with what feels natural. Walk confidently. Keep your head up mover like a monarch, because you are the Queen/King of Drama.

6) Be brave.
Don't be afraid to make a fool of yourself. As a monarch and a drama person, you must let people notice you. Make jokes, always steal the canter stage unless the limelight is on somebody else. Don't be rude or pushy. If you're a bad dancer, exaggerate it. Dance like there's no tomorrow and make a show. A Drama Queen/King's trade is an entertainer. If you have a flaw, make fun of it. Just don't be too obnoxious with it.
