Dirty rap, porno rap, porn rap, sex rap, or pornocore is a subgenre of hip hop music that contains lyrical content revolving mainly around sexually suggestive subjects. The lyrics are overtly explicit and graphic, often to the point of either cartoonishness or extreme offensiveness. Historically, dirty rap often contained a distinctly bass-driven sound, which arose from the popular Miami bass rap scene. However, dirty rap has recently been heavily influenced by Baltimore club, Ghetto house, and ghettotech. Many dirty rap songs have been used as soundtracks to pornographic movies in the 2000s, replacing the traditional porn groove.
