Part of the chorus is backwards. There was a lot of speculation that Missy was hiding a dirty message, but when reversed, the lyrics are simply the other part of the chorus: "Put my thing down, flip it, and reverse it."
Elliott revealed to Billboard
in a 2018 interview that it was a happy accident caused by the finger slip of an engineer.
"The reverse thing, that was a mistake," she said. "The engineer happened to hit something, and it just went backward, and I was like, 'Oh that's kind of crazy' because it went backward on the beat."
Elliott added: "So, after that happened, I said, 'Yo, keep that in there and I'm going to write around it.'"
