This game is usually played with 3 or more paticipants in any enviroment.

To play this game, first you must buy a muffin and hollow out the top to mid-center like a basin.

Next players "Circle jerk" into the muffin. Whoever is last to ejaculate into the muffin is the person who must eat the muffin, or they are bludgeoned by their friends.

Simply put, this game is "Last to beat it, eat it."

That Ryan kid came first, I think he's gay..
