Seu Madruga, known in Spanish as Don Ramón, is one of the main characters in El Chavo del Ocho, the Mexican sitcom created by Roberto Gómez Bolaños that became hugely popular across Latin America and in Brazil through its Portuguese dub. In the show he is the long-suffering neighbour who is often scolded, broke and unlucky, which made his exasperated reactions especially memorable. Short clips of his voice have since circulated online as reaction sounds, and this single word has become a compact way to declare that someone has failed.
