The line comes from Chaves, the Brazilian Portuguese version of the Mexican sitcom El Chavo del Ocho, created by Roberto Gómez Bolaños in the 1970s. The show became a lasting fixture on Brazilian television and its classroom jokes produced many quoted phrases. In Brazilian Portuguese the expression means oh how dumb, and online it turned into a ready made insult for wrong answers. Shared in videos, group chats and soundboards, it survives because even people who never watched full episodes recognise the voice, the rhythm and the mocking schoolyard tone immediately.
