Seu Madruga is the Brazilian Portuguese name for Don Ramón, played by Ramón Valdés in the Mexican sitcom El Chavo del Ocho, first broadcast in the 1970s and dubbed as Chaves in Brazil. The series became a staple of Brazilian television for decades, and short clips of its cast are now widely shared as reaction audios. This laugh survives alongside other short Brazilian laugh clips and the chipmunk laugh as a quick, recognisable cue for mocking, good-natured laughter online.
