The MLG horn grew out of the Major League Gaming montage style that spread across YouTube, where over-the-top edits celebrated impressive plays with loud sound effects, flashing text and slow motion. The air horn became one of that style's most recognisable signals, quickly adopted by parody videos and gaming creators who wanted an instant cue for hype or absurdity. Even as montage trends changed, the sound survived because it is short, unmistakable and easy to drop into almost any clip, keeping its place as a shorthand for an epic or ridiculous moment.
