The phrase is everyday Brazilian Portuguese for what is this, and this stretched version circulates mainly as a short forwarded WhatsApp audio. Its humour comes from how familiar the wording is, which lets anyone reuse it instantly without context or explanation. People pass it around in group chats and lift it into short videos as a standalone reaction to screenshots, strange finds and out of context messages. Because the delivery does all the work, it has stayed useful long after countless other novelty audios have faded from conversation.
