The airhorn is a real compressed-air horn heard at sports stadiums and on boats, and its sound was adopted by dancehall and reggae sound systems as a crowd-hype effect. A short sampled blast crossed over into internet culture through gaming montages and comedy edits, where it became shorthand for comic emphasis and fake celebration. Because the sound is instantly recognisable and needs no explanation, creators still reach for the quick airhorn hit to mark punchlines, wins and embarrassing fails across short-form video.
