The line comes from El Chavo del Ocho, the 1970s Mexican sitcom known in Brazil as Chaves, where neighbours in a humble courtyard constantly blamed the orphan boy Chaves for accidents and misunderstandings. The phrase 'tinha que ser o Chaves' became shorthand for that blame, repeated whenever his clumsiness was revealed. Decades of reruns on Brazilian television kept the show in popular culture, and the line later spread through memes, reaction videos and WhatsApp audios, where it still works as instant recognition for anyone who grew up watching Chaves.
