The shout comes from Kendrick Lamar's 2024 album GNX, in the second half of the track tv off, where he calls out producer Mustard, born Dijon McFarlane, who produced the song. The album arrived as a surprise release in November 2024 and the exaggerated delivery was quickly clipped, looped and reused across TikTok, Reels and short edits. Because the word is stretched far beyond a normal producer tag, it detached from the song itself and became a standalone reaction sound for reveals, entrances and over the top moments online.
