Chaves is the Brazilian title for El Chavo del Ocho, the Mexican sitcom created by Roberto Gómez Bolaños that became a long-running hit in Brazil through its Portuguese dub. Short catchphrases and reactions from the show have circulated for years as memes, reaction clips and soundboard sounds, especially among Brazilian viewers who grew up watching it on television. The repeated no no works because it is instantly recognisable even out of context, and its brevity makes it easy to reuse in short-form edits, chats and comedy videos.
