Faustão is the nickname of Fausto Silva, host of Domingão do Faustão, the long running Sunday variety show on TV Globo in Brazil. His loud Errou became one of his signature catchphrases when contestants gave a wrong answer on stage. Clips of the shout were later shared as short audios on WhatsApp, YouTube edits and Brazilian meme pages, detached from the original show. It remains popular because almost every Brazilian viewer recognises the voice and the meaning instantly, making it a shorthand for failure online.
