Penis Thresholder
The sexual act of your girl tying a piece of fishing string as tight as possible around the penis head. The penis, over time will lose blood circulation and fall off. Your girl then will take it, cook it into a meal for you and then eat it.
Guy 1: why are you holding your crotch?
Guy 2: my girlfriend is doing the whole "penis thresholder" thing.
