The phrase refers to Olavo de Carvalho, the Brazilian writer and commentator whose followers often repeated that he had predicted later political and cultural events. Shortened to Olavo avisou, meaning Olavo warned, it spread widely in Brazilian social media posts, comment threads and messaging groups as a shorthand reaction. Over time it moved beyond supporters and became a general meme, used ironically as well as sincerely, which is why the short clip now works even without any context about the original debate it came from.
