“Stir Fry” is the second single off Culture II. In the Pharrell-produced song, Migos drop fast food references and flaunt their success.

This marks the first time in a long time that the trio strayed away from their signature Atlanta trap sound and rap over a poppier beat.

According to Quavo, they ran into Pharrell in Los Angeles when the N.E.R.D frontman stepped into one of their studio sessions with a “pack” of beats from 2008 earmarked for the Atlanta trio:

We was in the studio in L.A. and he was in the next room. We had been running into each other, we’ve been cool, but he was over there working and he just stepped in because we just walk in everybody’s sessions and it’s love, and go to work. And Pharrell had, like, three or four beats, but the pack was from 2008, like, the old hard drive. He had the old pack. He said he was waiting on this moment. The genie way.

The beat was originally intended for an unreleased T.I. song. Twitter user Erik Anderson pinpointed the track as “Trap Nigga Hustle,” which was recorded two years prior to the Atlanta rapper’s 2014 album Paperwork. T.I. mentioned it during an interview with DJ Whoo Kid and previewed the instrumental in a Vevo segment about his car collection:
