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.

Kendrick Lamar screaming "Mustard" from the song "TV Off" on his new album GNX is now a popular meme. Here's why.

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.
