The air horn comes from sports stadiums and celebrations, where its loud blast signals hype and victory. It became an internet staple through MLG montage parodies and Vine-era meme edits, where creators spammed the horn for comedic emphasis. Bass-boosted remixes later took over on YouTube and TikTok, with the 420 label marking heavier, distorted versions favored in stoner meme culture. This style persists because the sound is instantly recognizable and cuts through any mix, making it a go-to punchline for pranks, edits and live streams.
