used in a game of pissflaps and ballsack
... 1 guy says ballsack the other has to say pissflaps louder then the first guy says ballsack even louder again until 1 is too embarrassed to continue (or passes out.. u know.. which ever suits)
this game works best on public transportatin (ie. bus) or restaurants
