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. In addition to the penis, fingers, clitoris, breast, or the tongue may be inserted into the hole. Glory holes are sometimes the topic of erotic literature, and pornographic films have been devoted to the uses of glory holes.
