Dirty blues

Dirty blues (also known as bawdy blues) is a form of blues music that deals with socially taboo and obscene subjects, often referring to sexual acts and drug use. Because of the sometimes graphic subject matter, such music was often banned from radio and available only on jukeboxes. The style was most popular in the years before World War II, although it experienced a revival in the early 1950s.

Many songs used innuendo, slang terms, or double entendres, such as Lil Johnson's "Press My Button (Ring My Bell)" ("Come on baby, let's have some fun / Just put your hot dog in my bun"). However, some were very explicit. The most extreme examples were rarely recorded at all, a notable exception being Lucille Bogan's obscene version of "Shave 'Em Dry" (1935), which Elijah Wald has noted as "by far the most explicit blues song preserved at a commercial pre-war recording session".
