The sound comes from the MLG montage parody culture that spread on YouTube in the early 2010s, where editors layered air horns, hit markers and sponsor jokes over Call of Duty clips. The horn itself is a sampled stadium air horn, repeated and boosted until it became the signature MLG air horn heard in countless compilations. As montage parodies faded, the blast survived as a standalone meme sound on TikTok, Discord and soundboards, still instantly signalling ironic hype and early internet gaming humour.
