A game where several men gather around a cracker (I always picture a stoned wheat thin) and furiously masturbate onto it. Whoever ejaculates first wins. By a similar token, the loser is he who ejaculates last. The loser must consume the cracker as a penalty for sloth.
I got the clap from losing a game of cracker jack in college.
