The shout comes from Kendrick Lamar's song tv off, released on his album GNX in 2024 and produced by Mustard, whose name is yelled at the start of the track. The raw, over-the-top delivery stood out immediately from a typical producer tag, and clips of the moment spread quickly on TikTok and other social platforms, where creators reused it as a hype sound. It is still used because it is short, instantly recognisable and works as a punchline on its own, even for viewers who have not heard the full song.
