Woshambo 

Wo Sham Bo is a game which is were two or more induviduals take it in turns to kick each other in the nuts the first person to fall over is the loser.

An example of this is in the south park episode "Mecha Streisand" where Cartman chalanges Kyle to a game of woshambo (pronounced as Wo Sham Bo)to try and get something from him.
