The air horn became a staple of MLG montage parodies that spread on YouTube in the mid 2010s, where fast Call of Duty edits paired trick shots with Doritos, Mountain Dew jokes, and repeated horn blasts for comic excess. The horn itself is a compressed stadium air horn sample layered on itself to sound bigger and more chaotic. As montage parody faded, the sound survived as a standalone reaction and hype effect, with quieter edits like this one made so creators could reuse the joke without the original volume spike.
