The phrase formato de ursinho translates from Portuguese as teddy bear shape, and the clip circulates online mainly as a short reaction sound rather than as part of a longer performance. Its appeal comes from the mismatch between a matter-of-fact description and a cute or rounded subject, a contrast that fits short-form video, memes and chat replies. Because the line is brief, easy to recognise and instantly playful, creators reuse it whenever a visual comparison does the comedy work for them, keeping the sound current long after its first shares.
