Put it at the end of a voice-note rant, straight after the last long message, then follow it with a fart sound for a second punch and a censor beep to cut the reply short before the chat moves on.
About this sound
A loud Portuguese voice clip of a man shouting at someone to stop sending voice messages because he is on the toilet, delivered in a hurried, irritated tone that leans into the crude excuse. It feels blunt, awkward and instantly funny, like a reply that ends a chat by oversharing. It comes from Brazilian voice-message culture, where such recorded replies were passed around in groups before reaching soundboards.
