Get the Gerbillingmug. Generally performed by homosexuals; the act of stuffing a gerbil up one's butt. Once in the folds of the anus, the gerbil becomes claustrophobic and claws and digs, giving the homosexual pleasure. A string is often tied to the gerbil's tail to allow the gerbiller to pull it back out. Toilet paper roles may also be used to help launch the gerbil into the homosexual's butt.
