There is no widely documented origin for this short clip, which circulates mainly as a user-generated soundboard sound rather than a line from a well-known film or show. Its appeal is deliberately low-effort and gross-out: one blunt announcement that needs no context to be understood. Shared in edits, streams and group chats, it works because the subject is both mundane and taboo, so the joke lands instantly even for viewers who have never heard it before. That simplicity has kept it in rotation as a quick reaction sound.
