Faustão is the stage name of Brazilian presenter Fausto Silva, whose lively Sunday variety show made him a household name in Brazil and turned several of his exclamations into national catchphrases. Ô loco bicho became one of the most quoted, used whenever something surprising, impressive or plainly absurd happened on screen. As clips circulated on social media and messaging apps, it moved beyond television and became a ready-made reaction for Brazilian internet humour, still recognised instantly even by viewers who never watched the original broadcasts.
