The line comes from Tropa de Elite, the 2007 Brazilian film centred on Captain Nascimento and Rio de Janeiro's elite police squad. Nascimento became one of Brazilian cinema's most quoted characters, and his blunt, exasperated delivery made lines like this one easy to lift into memes, reaction videos and WhatsApp audios. The phrase translates roughly as it could only end badly, which explains its staying power: it fits almost any clip where someone ignores an obvious warning and the outcome is exactly the mess viewers expected.
