This sound comes from a user-uploaded soundboard with almost no documented history, so its exact origin is unknown, and the page treats it as a community-made meme clip rather than a quote from a known show or game. The phrase 'who goes there' is a classic sentry challenge, long used in cartoons, games and comedy sketches whenever someone is caught sneaking around. Paired with a cartoonish zap, it found a second life online as a short sting for ambushes, jump scares and caught-in-the-act edits. Its charm is the instant setup: one jolt, one question, and the joke lands.
