A game in which several males will have a contest masturbating on a biscuit. The one who ejaculates last will lose, meaning he will have to consume the biscuit.
"Mikey and Jason were playing the mushy biscuit game, and because he was so shy because of his crooked penis, Jason came first, and Mikey had to eat that soggy mushy mess of a biscuit.. he almost puked."
