Glory hole
A glory hole (also spelled gloryhole and glory-hole) is a hole in a wall or partition, often between public lavatory cubicles or sex video arcade booths and lounges, for people to engage in sexual activity or to observe the person on the opposite side. Glory holes are especially associated with gay male culture and anal or oral sex. They are not exclusively favoured by gay people, and have become more commonly acknowledged as a fetish for heterosexual and bisexual individuals. In more recent years, public glory holes have faded in popularity in many countries, though some gay websites offer directories of remaining ones. Glory holes are sometimes a topic of erotic literature, and pornographic films have been devoted to their use.
