The sound comes from a YouTube Poop by Brazilian creator Mestre3224, a style of edited video that remixes television clips into absurd new jokes. It isolates a moment featuring presenter Ratinho and stretches his shout into the long, exaggerated form heard here. Shared as a short soundboard clip, it has travelled through Brazilian meme edits and reaction videos, where its brevity and recognisable voice make it easy to drop into unrelated scenes. It remains in use because the joke needs no context: one loud, drawn-out shout is enough to signal mock surprise.
