The air horn itself has long been a stadium and celebration noisemaker, but its meme life began with Major League Gaming montage parodies, where editors layered exaggerated sound effects over gameplay to mock over-the-top esports hype. The single loud blast became shorthand for an epic play, a joke landing, or a moment played up for laughs. From YouTube montages it spread to TikTok, Twitch clips and reaction videos, where its brevity makes it easy to drop into almost any edit. It endures because listeners recognise it instantly, even without context, as a signal for hype.
