Seu Madruga is the Brazilian Portuguese name for Don Ramón, played by Ramón Valdés in El Chavo del Ocho, the Mexican sitcom created by Roberto Gómez Bolaños. Dubbed as Chaves in Brazil, the series became a lasting television staple and its characters' catchphrases entered everyday slang. Short clips of Madruga scolding others spread through Brazilian social media, chats and meme edits, where que burro works as a shorthand insult for an obvious blunder. Its continued use comes from instant recognition among fans who grew up hearing the dub.
