Listed with the short description calling it the most common sound in the toilet, this 3.4 second clip has no confirmed film, game or creator source. It spread as a generic soundboard staple for toilet humor instead, passed around in meme edits, prank videos and group chats, often alongside a fart sound, where a blunt poop joke needs no setup. Its three flat repetitions make it easy to loop or cut, and it stays popular because bathroom humor remains a universal shortcut for childish, gross out comedy online.
