This sound is the familiar air horn effect widely used across prank clips, meme edits, DJ-style transitions and short-form videos. Rather than belonging to one specific character or scene, it spread online as a quick way to signal shock, chaos or comic interruption. Its popularity comes from how instantly recognizable and aggressively loud it is, much like a vuvuzela in sports clips. Creators still use it because a two-second horn blast can completely change the tone of a moment without needing any dialogue.
