Triple horn sounds have circulated on soundboards and short video apps as a generic attention grabber rather than a clip tied to one film or show. The three repeats became the standard form because one honk reads as an accident and two feel unfinished, while three lands like a deliberate announcement. Editors keep it in meme folders alongside air horns and car alarms, using it for entrances, interruptions and mock emergencies. Its lack of words or music makes it easy to drop over any footage.
