The MLG air horn grew out of Major League Gaming montage parodies, where editors layered loud, over-the-top effects over gameplay clips to mock and celebrate dramatic moments at the same time. The air horn itself became shorthand for instant hype, and pairing it with a shouted yeet adds a newer internet slang punch to the classic effect. As short-form video and gaming edits spread the sound, creators kept returning to it because it is instantly recognisable, easy to drop into a single beat, and works without any explanation for viewers who already know meme culture.
