Não Era Eu is a song phrase performed by Brazilian sertanejo duo César Menotti e Fabiano, a pair known for romantic sertanejo songs that are widely shared across Brazil. The short excerpt has circulated beyond the full recording through soundboards and messaging apps, where listeners save it as a compact reaction sound rather than a song to listen to in full. Its staying power comes from the universality of the denial it expresses, which fits jokes, arguments and plot twists in Portuguese-language videos. Its short, recognisable form needs no explanation in a scene.
