Petista is the common Brazilian nickname for supporters of the Partido dos Trabalhadores, the Workers' Party long associated with Luiz Inácio Lula da Silva. Clips mocking or celebrating that side spread constantly in Brazilian WhatsApp groups and short video edits, alongside opposite slogans like Faz o L. This shout follows that same back and forth tradition, using a short insulting chant rather than a speech excerpt. Its popularity comes from how instantly Brazilian viewers recognize the target and the triumphant tone, even without any visual context.
