The signs and their descriptions;

Aries: Livin' it up with their friends. They'll probably break something, walk away and pretend nothing happened.
Taurus: Carefully outweighing the pros and cons of getting more food.
Gemini: Being loud as hell. It feels like they're everywhere. Someone's probably convinced they;re secretly The Flash.
Cancer: Surgically glued to that one friend they came with.
Leo: All over the place talking to people. Probably the host.
Virgo: Sitting awkwardly in a corner. Trying to resist the temptation to take out the book they brought with them.
Libra: Taking care of their friends while they throw up.
Scorpio: Silently observing everyone getting crazier by the hour, they spend the night making fun of them with snarky comments.
Sagittarius: The one that ends up spending the night throwing up. Or they have a stronger stomach and make an ass of themselves.
Capricorn: They just judge everyone. They don't go off their friend's side. The designated driver, probably.
Aquarius: Depending on their mood, they'd either go crazy or stay in a corner judging everyone.
Pisces: Used to be the designated driver, but their memory sucks and they accidentally drink. Probably just chills in a corner if they're friends aren't pushy.

I got my star sign Virgo this time! This would so be me, that's if I even turn up in the first place :P And a bit of Scorpio too!

Got scorpio. But also agree with my capricorn sign.

I think so & maybe Aquarius as well :)

I got Cancer but I am a pisces

They should be get drunk, maybe high and dance with friends until sun comes up :P

Ha! My sign.
Honestly it was a touch choice between this and talking to everyone. But Leo is good too.
