The phrase itself is a Portuguese wordplay on the famous Hamlet question, replacing being with being a corno, Brazilian slang for a man whose partner has cheated on him. The exact original recording is not widely documented, but the line circulates as a short, shareable audio meme in Portuguese-speaking communities, especially in jokes about relationships, jealousy and betrayal. Its appeal comes from that clash of registers: a grand philosophical question used for a blunt, everyday insult, making it easy to reuse across short videos and reaction clips.
