The phrase comes from Brazilian singer and internet personality Inês Brasil, whose eccentric audition video for Big Brother Brasil went viral in 2013. In the video she performs, dances, and drops several quotable lines in drag slang, with mona used as an affectionate term for a fellow queen or friend. Clips were reposted across YouTube, Facebook, and later TikTok and WhatsApp, turning this line into a lasting Brazilian meme for confidence, visibility, and shameless self expression.
