The Deez Nuts joke is a long-running schoolyard prank in which an innocent-sounding question is designed to make the listener say a phrase that sets up the punchline. It found a second life online as short reaction audio, spreading through memes, prank videos, and short-form edits where the reveal matters more than the setup. Because the joke is instantly recognisable and needs no explanation, creators still use it to mark the exact moment a trick lands, especially in fast, low-effort comedy built around a single twist.
