The air horn became a staple internet sound effect through meme edits, reaction videos and short-form comedy, especially in loud montage-style content. It is widely used as an exaggerated cue for hype, interruption or deliberate sensory overload. Online, it is closely associated with remix culture and over-the-top editing styles, including MLG-era videos where sounds like the MLG air horn helped define the joke. Its staying power comes from being instantly recognizable and easy to time with visual punchlines.
