The horn comes from Jamaican dancehall sound system culture, where DJs and selectors used air horns to hype the crowd, salute a performer, and mark a standout lyric or drop. As dancehall, reggae, and hip hop travelled worldwide, the horn travelled with them into clubs, mixtapes, radio drops, and later online soundboards and video edits. It survived because it is instantly recognisable and needs no explanation, so creators still use it to signal excitement, approval, or a moment worth celebrating.
