In addition to tapping singers SZA and Deyra Barrera, the 17-time Grammy winner used production from frequent Taylor Swift collaborator Jack Antonoff as well as Mustard, the stage name of Dijon Isaiah McFarlane, who produced Lamar’s mega-viral hit “ Not Like Us .”

Where does Kendrick Lamar's viral 'mustard meme' come from and what song on his new album 'GNX' does it originate from? Here's the meme and its origins explained.

Lamar’s “Mustard” shout out is all over the internet, including brands like McDonald’s, the Minions, and Shrek. There are Simpsons references, Peanuts -style drawings, and TikTok edits. A pastor yelled “Mustard” during a church service, as seen here, and even Lizzo got involved.
