The phrase is everyday Portuguese, commonly said to children as a mild correction, which is part of why Brazilian and Portuguese speaking audiences recognise it instantly online. As a soundboard clip it circulates mainly as a reaction audio, shared in chats and short videos whenever strong language appears unexpectedly. Its humour comes from using a polite, almost old fashioned rebuke in loud, chaotic contexts like gaming or livestreams. Because the meaning is clear even without translation, editors keep reusing it as a clean punchline that needs no extra explanation or setup for viewers.
