Tiddlywinks is an indoor game played by men played on the floor or a bed. Players stroke their shafts until climax, thereby propelling semen, called "winks", into the air. The offensive objective of the game is to score points by sending their own winks into the "pot", the other players mouth. The defensive objective of the game is to prevent your opponents from potting their winks by "squopping" them: shooting your own winks to land on top of your opponents' winks. As part of strategic gameplay, players often attempt to squop their opponents' winks and develop, maintain large mouthfuls of winks.
