A merkin (first use, according to the OED, 1617) is a pubic wig, originally worn by prostitutes after shaving their genitalia to eliminate lice or disguise the marks of syphilis. There are many different ways of wearing a merkin, although most involve placing the merkin on the vulva or the scrotum.[citation needed]
The term is also applied to decorative (typically sequinned) patches commonly sold in sets with nipple tassels or "pasties" and are enjoying new popularity as part of the costume of new burlesque adult entertainment.
Merkins are currently used in films where they are worn by actors and actresses to prevent inadvertent exposure of the genitalia during nude or semi-nude scenes. If no merkin were worn, it would be necessary to restrict the shot to exclude the genital area; with the merkin in place brief flashes of the crotch can be used if necessary. The presence of the merkin protects the actor from inadvertently performing 'full-frontal' nudity (their contract may specifically require that nipples and genitals are covered in some way), and can help ensure that the film achieves a more acceptable MPAA rating.
