yeah a drink or two might be okay. Unless you're a stupid drunk I went to dance drunk with some friends I acted ok, but my friends were an embarrasment, I had to leave it was sad. The was a dance held in a church, I made sure I didnt get pissed drunk and had fun until, my one friend started air thrusting towards girls. And the other decided he would try and "breakdance" aka a shitty attempt at cartwheel, and teddy bear handstands.
So as long as you can just have some fun and not act like an ass, then a shot or two might make you dance.
