The phrase 'Não é o Carlos' circulates online as a standalone reaction audio in Portuguese-speaking meme and chat culture, where short voice notes are reused as punchlines. Its appeal is its specificity — a name nobody in the conversation may know — which makes the denial funnier when applied to unrelated mix-ups. Shared as an MP3 and on soundboards, it is used for wrong-name gags, doppelganger posts and playful arguments, and remains popular because the line needs no context to land.
