The line circulates as a Brazilian Portuguese meme audio, shared in short videos and message threads where someone wants to call out strange, rambling or unbelievable talk. Its appeal comes from its directness: instead of a long argument, the speaker simply names the person and questions the conversation itself, which makes it easy to reuse in many situations. Because the phrase is short and memorable, creators keep pairing it with reaction shots, dubbing it over confusing dialogue, and sending it as a quick reply when words alone would take too long to explain the disbelief.
