Popular in Truck Stops from what I've heard!
A glory hole (also spelled gloryhole and glory-hole) is a hole in a wall, or other partition, often between public lavatory stalls or adult video arcade booths for people to engage in sexual activity or observe the person in the next cubicle while one or both parties masturbate. The partition maintains anonymity. Body parts including fingers, tongue, and penis may be used for anonymous oral, vaginal and/or anal intercourse. Erotic literature and pornographic films have been devoted to the sexual uses of glory holes.
