Olavo de Carvalho was a Brazilian philosopher and writer whose online lectures and political commentary attracted a large following in Brazil, and the phrase Olavo tem razão became a shorthand slogan among his supporters. It spread through social media clips, reaction videos and messaging groups, where it was quoted both sincerely by admirers and ironically by critics. Because the line is short, recognisable and politically charged, it continues to circulate in Brazilian internet culture as a quick way to signal agreement, mock an opponent, or close a debate without further explanation.
