The sound comes from Brazilian comedian Diogo Defante and is linked to his video about Jair Bolsonaro on Roda Viva, presented as questions that were cut from the interview. The short phrase caught on because it is easy to quote, easy to recognise in Portuguese, and instantly signals disbelief or a challenge. Shared widely as a meme and reaction clip, it moved beyond its original interview context into everyday online humour, where creators reuse it whenever someone says something bold, suspicious or hard to believe. Its brevity keeps it useful for short videos and chats.
