Passa ou Repassa is a Brazilian television game show broadcast on SBT, where two teams compete in fast rounds of questions, games and physical challenges. The siren works as a studio buzzer, marking a lost round, an expired timer or a wrong move. Clips of the show have long circulated in Brazilian social media, online groups and reaction edits, where the short, unmistakable sound is reused far beyond its original studio context. It remains popular because it instantly tells Brazilian viewers that something has just gone wrong, without needing any explanation.
