OK, firstly.. everyone needs a same-size drink. Sit in a circle, and the first person says "I never _________" just say it was a room full of only girls someone could say something funny and absolutely impossible. If you have done what the person says you must take a sip from your cup. It continues around the circle and you can play for as long as you like, and in the end the person who drank their drink the most is the winner.
