Márcia Sensitiva is a Brazilian psychic and media personality known for her calm, spiritual advice. Short clips of her saying relaxa began circulating on Brazilian social media and WhatsApp as a lighthearted way to tell someone to calm down, and the word quickly became one of her most recognisable catchphrases in meme edits. Because it is short, instantly understandable even to non-Portuguese speakers through tone alone, and easy to drop over stressful moments, it remains a popular reaction sound in Brazil and among Portuguese-speaking creators.
