The clip comes from a 2021 commentary by Brazilian journalist Reinaldo Azevedo, who was responding to Senator Eduardo Girão's claim that the Coronavac vaccine contained aborted fetuses. Azevedo used the blunt Portuguese phrase to reject the claim as ignorant, and the moment was later clipped and shared as a reaction sound in Brazil. It remains popular in political discussions and WhatsApp debates because it gives listeners a short, quotable way to dismiss misinformation without a long explanation.
