D4C, short for Dirty Deeds Done Dirt Cheap, is the Stand of Funny Valentine, the main antagonist of the Steel Ball Run arc of JoJo's Bizarre Adventure, and its power lets him move himself and others between parallel dimensions. Fans lifted the warped shifting noise associated with that ability into a standalone teleport sound for short-form edits, where it quickly became shorthand for a reality change rather than a simple jump cut. It remains popular because JoJo edits still rely on instantly recognisable audio cues to sell impossible movement.
