I have searched but couldn't find is this exist in pua community. I saw this game while watching Lost. Sawyer and Kate was playing this game and I think it is a good and fun game for getting know each other. Here is the game:

I never.. can be played with several players. There is no ending time. There is one rule, saying TRUTH! and game is based on turn.

A player just say such as: i never eat sushi. If anyone in the group (including the player asked) had eat sushi, sips his/her drink. if not, then doesn't sip. There is no answer, just drink or not drink. Then next player asks... get it?

I think best phase is isolation. it looks similiar to question game. First start with normal questions then go on sexual (i didn't test it yet)
