Faz o L began as a campaign gesture for Luiz Inácio Lula da Silva during Brazil's 2022 presidential election, with supporters forming an L with thumb and index finger to represent his initial. The simple sign spread quickly through rallies, social media and TikTok, where it became both a badge of support and a widely remixed meme, later used sincerely, ironically and in rival edits. A related jingle version circulates as Faz o L Vinheta. Its staying power comes from that instant visual shorthand: one letter instantly signals a side, a victory or a joke.
