The phrase itself is Brazilian Portuguese slang, roughly meaning something is so astonishing that it is jaw-dropping, expressed in deliberately crude, comic language. As a short voice clip, it circulates in Brazilian meme culture as a reaction sound for unbelievable moments, often shared in group chats and reused in short videos where a spoken punchline works better than a text caption. Its appeal is the contrast between the everyday shock it describes and the exaggerated, vulgar delivery, which makes a familiar reaction feel louder and funnier.
