The file is credited to DJ Kier (Kier Layos) and titled Horn #2 in its metadata, and it circulates online as a short standalone soundboard effect rather than a line from a film, show or game. Like an MLG air horn, it is prized for its instant, unmistakable blast, which is why editors reuse it across short videos, streams and meme edits instead of recording a real horn. Its two-second length keeps it easy to reuse, and its clean ending makes it simple to loop or layer under other clips.
