tinklebutt
One whose anus is frequently filled with urine, most often for sexual pleasure; synonymous with "turd burglar" and "doughnut puncher", as the recipients of these golden enemas are frequently of the homosexual persuasion.
God my girlfriend's friend is such a tinklebutt! That piss glistener's golden enema leaked all over my back seat when I gave him a ride home from his doughnut punching boyfriends house.
