This audio circulates mainly in Brazilian meme spaces under titles that mention Carlinhos and a urine joke, but its exact original source is unclear. It became recognizable through reposts on soundboards, meme pages and WhatsApp shares, where people used it for shock humor rather than for a specific character reference. Its staying power comes from how blunt and uncomfortable it is: even listeners who do not know any backstory understand the joke immediately, so it keeps reappearing in cursed edits, reaction clips and deliberately outrageous chat posts.
