Armenian Tail Whip
While in the process of pooping during sexual intercourse, a man allows his feces to secrete part of the way out of his anus. Once the desired length of out-of-butt poop is achieved, the man swings his feces into the face of the woman (or man) whom he is engaged in sexual acts with. His stool is then smeared upon the face of the woman (or man) whom was hit with the poop, creating a frothy mustache effect.
Steven: Did Joey grow a mustache?
Jeremy: No, John just gave him the Armenian tail whip.
