Pongale cero, meaning give him a zero, became a familiar classroom put-down associated with El Chavo del Ocho, the Mexican sitcom created by Roberto Gomez Bolanos in the 1970s. Its school scenes, centred on Professor Jirafales and his pupils, gave the phrase a clear setup: a bad answer followed by a merciless grade. Clips and remixes later circulated on video and meme pages across Latin America and Spain. It remains popular because the judgement is instant, understandable even for non-Spanish speakers from tone alone, and reusable for any visible failure.
