The air horn blast became a staple of Jamaican dancehall sound systems before crossing into hip hop, reggae and EDM in the 1990s and 2000s. Radio DJs and mixtape hosts used repeated honks to signal excitement, rewind a track or stamp their name on a mix. From there it spread to sports arenas, party remixes and internet memes, where the sheer loudness turned it into shorthand for hype. Even a single blast now instantly suggests a celebration is starting.
