The exact origin of the Wander McMooch noise is unclear from its user upload, but its published note sums up the joke as gotta go fast. Online it circulates as a tiny reaction-style meme clip for rushed exits, failed sneaking, and sped-up skits, usually under two seconds long. Its appeal is the same as a classic cartoon chase cue: instant motion without explanation. Because it is so short, editors reuse it as punctuation rather than background, keeping it tied to fast comedy edits.
