It is when you are erect and you get the girl to shit on you, then you take the feces and make little balls of shit. You then pull your penis back like a catapult and you put the shit ball under the head of your pecker pipi, then release the little turds into her mouth. This way you guys can have fun while having sex, its like diner in bed.
