The phrase comes from Javier Milei, the Argentine libertarian politician and president known for blunt, confrontational speaking in interviews and public appearances. Clipped into a two second sound, preparate porque la vas a pasar mal spread on soundboards and in Spanish speaking meme edits as a reusable threat line. Creators use it outside politics as well, applying the warning to games, sports, school and everyday arguments. Its popularity comes from how instantly understandable the line is, even when the situation that follows is minor or completely absurd.
