Faustão, whose real name is Fausto Silva, is one of Brazil's best-known television presenters, famous for his energetic Sunday variety show and its audience games. In those segments, Errou was his instant response when a contestant gave an incorrect answer, and the word stuck as a catchphrase. Shared first as a television moment and later as a short audio clip in memes, reaction videos and messaging apps, it remains a quick shorthand in Brazil for calling out a mistake with humour rather than malice.
