Buzina do Sergipe takes its name from the Portuguese word for horn and Sergipe, a state in northeastern Brazil, and it circulates mainly as a Brazilian meme audio. The clip spread through soundboards, WhatsApp shares and short video edits where a long horn blast is used as a punchline for traffic jokes, arguments and unexpected interruptions. Its appeal comes from how familiar and over the top the noise feels, making even an ordinary scene sound like a street level emergency that everyone nearby can hear.
