Air horns were originally used at sporting events, on boats and at parties to signal and celebrate, producing a loud blast from compressed air. Online, the sound became a staple of MLG montage parodies in the early 2010s, where editors layered the MLG air horn over trick shots and Doritos-fuelled gaming clips for comic excess. This mega loud version pushes that joke further with boosted gain and distortion. It remains popular on soundboards and in Discord calls because one blast instantly signals irony, hype and deliberate annoyance.
