definition as per wikipedia
"A merkin is a pubic wig. Merkins were originally worn by prostitutes after shaving their genitalia, and are now used as decorative items, erotic devices, or in films, by both men and women. The female version is usually made of fur, linen or some soft version of cloth, while the male version is usually made of loops, chains or metal, much more closely related to the codpiece"
