“WAP” (Wet-Ass Pussy) is Cardi B’s fourth number 1 hit on Billboard, her first release of 2020, and her first single since 2019’s “Press.” It is expected to appear on her upcoming second studio album and marks her first collaboration with Megan Thee Stallion.

The track is built around a bass-heavy trap beat and a looping sample of DJ Frank Ski’s “Whores In This House.” The song’s raunchy lyrics detail Cardi and Megan’s sexual fantasies.

According to Cardi, the song is so explicit Atlantic Records was worried about its release, and even asked Cardi to put Megan on a different song:

>When \[the label\] heard the song they were like, “We really like it, but that song is so explicit.” … They were like, “Can you please get another record and you could put Megan on it?” And I was like, “No.”

Like other sex-positive songs by female artists, these lyrics sparked online controversy. However, they were also widely praised for their message of female empowerment and sexual liberation.

The pair first revealed the song on August 3, 2020, with an announcement that the music video would premiere alongside its release three days later.
