A game in which at least 2 people (can be several) sit around each other. Speaking in regular conversation, or watching TV or any another activity, but if anybody says a word beginning with the letter B, they must say BB, or they receive a punch to the shoulder by another player, if they do not, they keep receiving punches.
Guy 1: Hey, lets play BB!
Guy 2: Okay.... Anyway, the other day one of the popular kids was staring at me from the other end of the hallway, what's her name again? Beth? Betty? B- (Person 2 gets punched in the shoulder by Person 1 several times)
Guy 2: BB, BB!
