The phrase comes from everyday Spanish slang, where qlos is a clipped spelling of a rude word for lazy people being told off. No single confirmed movie, show or creator is tied to this recording, so its history is mainly online. It spread as a shareable soundboard clip and short audio for chats, especially among Spanish-speaking users who use it to tease friends, classmates and coworkers. Its short length and clear shouting make it easy to reuse as a reaction, which is why it keeps appearing in meme edits and joke alarms.
