take ipctures, eat, dance, party, other stuffs for fun. Some events happen after the prom. If you know what I mean.
People usually hang out before prom and take pictures/ go out to dinner. Then you go to prom and keep hanging out and dancing and just having fun. After prom people with either go to breakfast, go bowling, or go to a party. A lot of people end up drinking and hooking up...but you totally don't have to do that if you don't want to.
what happens is just magical you don't just dance you might have your first kiss you might have a chance to fall in love (inless your taking your cusion that is just so wierd)! but i hope you have a good time :) :) :) :) : :) :) :) :) :) :) :) :) :( OOPS :):):):):):) ;)
