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.
About this sound
A short Brazilian voice clip saying 'o que é isso' with a stretched, shocked delivery, popular as a WhatsApp reaction for confusing or absurd moments.
This is a quick Portuguese voice reaction that translates to what is this, delivered with the final word stretched out into a long, bewildered issooo. The tone is pure disbelief, half shocked and half amused, like someone has just opened a message they cannot explain. At only two seconds long it lands instantly, with no build up needed. The exaggerated drawl turns a simple question into a punchline, making whatever image, video or statement came before it feel even stranger and funnier to the viewer watching along.
