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.

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 .”

Kendrick Lamar's booming shout-out to Mustard on GNX‘s "TV Off" has taken social media by storm and even brands like McDonald's have absorbed the trend. Lizzo is clearly a fan of the move and she pulled up to Kai Cenat's stream over the weekend with SZA and broke out into a Lamar imitation giving Mustard a shout-out of her own.
