The line comes from a clip of Maria do Rosário asking 'Mas o que é isso?' in Portuguese, and it spread online as a short reaction sound rather than as part of a song or scripted sketch. Because the phrase is simple, instantly understandable to Portuguese speakers and easy to drop into a video, it was picked up by meme pages and creators for moments of confusion, surprise and disbelief. Its short length and clear delivery have kept it useful for reaction edits, WhatsApp messages and short-form videos, where a quick, relatable question can punctuate an unexpected reveal.
