Without a confirmed source work, character, or creator, Diarreia Fudida circulates mainly as a short Portuguese language meme sound shared on soundboards and in chat groups. Its appeal comes from the blunt, vulgar phrasing, which Brazilian and Portuguese speaking users recognise instantly even out of context. Clips this brief travel easily between videos, streams, and messaging apps, where they become reusable reactions for stomach trouble, bad food, and toilet humor. It remains used because the gross out meaning is clear in under two seconds.
