Botão do Arroto is Portuguese for burp button, a name from Brazilian soundboards where short bodily-noise clips circulate as instant joke buttons. The clip spread in the same way as the fart button, shared for WhatsApp pranks, classroom jokes and quick meme edits rather than from a known film or show. Its appeal is simple timing: one press delivers an unmistakable, rude noise that needs no context or translation. That portability has kept burp sounds popular across prank compilations and reaction videos, even as specific trends change.
