Carnet Enfermo circulates mainly as a WhatsApp audio in Spanish-speaking groups, especially in Chile where Tío René Puente built a following for short, quotable voice notes that get forwarded as reactions. The phrase plays on the carnet, the Chilean ID card, being presented as proof of illness, turning a bureaucratic excuse into slang for calling in sick. As WhatsApp forwarding spread the clip beyond Chile, it joined a wider set of sick-day jokes, including the Brazilian É q eu tô meio gripadinha, and remains a shorthand reply in chats.
