The sound comes from the MLG montage parody era that took over YouTube in the mid 2010s, when editors layered Doritos, Mountain Dew and exaggerated effects over Call of Duty clips. The core MLG air horn was borrowed from sports stadiums and reggae dancehall samples, then repeated in quick bursts to mock overly serious highlight reels. Triple blasts like this version became a shorthand for fake hype, spreading to Twitch, Vine and gaming Discord servers where it still signals an ironic celebration.
