The phrase comes from Portuguese internet slang sharing, where short spoken lines about everyday apps are clipped and passed around as reactions. Tchesca fica no Facebook translates roughly to Tchesca stays on Facebook, and that blunt, specific name plus platform reference is what made it memorable. It spread as a WhatsApp and social media audio because it fits a very common situation without needing context. It remains used for light teasing about screen time, loyalty to one platform, and friends who are easiest to reach on Facebook.
