The shout comes from Kendrick Lamar's 2024 album GNX, where it opens the track TV Off and credits producer Mustard, whose DJ tag has long appeared on his beats. Fans clipped the exaggerated delivery and shared it across TikTok and other social platforms, where it became shorthand for a big moment arriving. Its popularity grew because the delivery is hard to miss and easy to imitate, and creators kept reusing it for entrances, reveals and jokes about the album itself.
