This clip has no single identifiable source, character, or original recording behind it, which is common for short bathroom sound effects shared across soundboards and meme pages. Its popularity comes from its recognizability rather than a famous scene, with Portuguese-language searches for diarrhea and fart noises showing how often creators look for exactly this kind of crude gag. It survives because the joke is universal, instantly understood without dialogue, and easy to drop into pranks, reaction videos, and short-form comedy where a single disgusting noise does the work.
