Its original source is not clearly documented, so it is best understood as a short Portuguese-language meme clip that circulates online through soundboards, edits and chat shares rather than as a line from a known film, show or song. The appeal is in its specificity: naming Kia and Marta's brother turns a private-sounding joke into a reusable reaction, and that personal, name-based humour travels well in short videos and group conversations. Because the clip is brief and easy to recognise, it keeps being reused whenever that inside-joke moment fits.
