"Darling Nikki" is a song produced, arranged, composed, and performed by American musician Prince, originally released on his sixth studio album Purple Rain (1984). Though the song was not released as a single, it gained wide notoriety after Tipper Gore pointed out its sexual lyrics—in particular an explicit reference to female masturbation—and was partly responsible for the creation of the Parental Advisory sticker. The song tells the story of a "sex fiend" named Nikki who seduces the singer.”

“Darling Nikki was discussed a lot in the media in 1984-85. Tipper Gore (author and wife of Al Gore), having overheard her eleven-year-old daughter, Karenna, listening to the track, was inspired to found the Parents Music Resource Center. The Center advocated the mandatory use of a warning label ("Parental Advisory: Explicit Lyrics") on the covers of records judged to contain language or lyrical content unsuitable for minors.”
