Keyz explained to Genius
that the duo maintain a database of potential songs to sample (for "Birkenhead" they flipped Project Pat's "Chickenhead"). They heard DJ Frank Ski's "Whores In This House" playing in an Atlanta club and immediately recognized it as a great track to use on a beat.
Ayo added that when they heard Cardi was working again, they sent her a pack of beats, including the one they'd done based around "Whores In This House."
"It was like, 'If it doesn't fit her, let's go for the City Girls or Megan Thee Stallion,'" he said. "It's crazy that it ended up being Cardi B featuring Meg."
