This kind of loud horn sound is widely used online as a general-purpose reaction effect rather than being tied to one specific character or scene. Short horn blasts became especially common in meme edits, gaming montages, and prank-style videos because they instantly signal surprise, panic, or exaggerated importance. It remains popular because the sound is simple, recognizable, and easy to drop onto a cut for a fast comedic payoff. Creators often use it alongside other impact sounds such as the MLG air horn or metal pipe clang.
