A short, loud car horn blast used as a jump scare sound effect for pranks, memes and reaction videos. It adds a sudden shock to fun edits and surprise moments.
Buzina susto is a brief, sharp horn blast that hits suddenly and cuts off almost as fast as it starts. In Portuguese, the name roughly means a scare horn, and that is exactly how it plays: a loud, blaring car horn with no buildup, no melody and no warning. At just over half a second long, it works as an instant jolt, making a viewer flinch, laugh or look up from scrolling. Creators use it to punctuate a reveal, interrupt a quiet moment or underline a prank gone wrong, because the sound feels urgent and slightly absurd at the same time.
Buzina susto is not tied to one film, show or song, but to the wider online habit of using a car horn as a sudden scare. Its Portuguese wording suggests a horn meant to startle listeners, and it appears in prank and comedy clips, where a loud horn replaces a scream or a dramatic sting. Because the clip is only about half a second long, it fits into short videos, reaction edits and soundboards, and creators keep returning to it for the same reason: a horn is instantly recognisable, hard to ignore and funny when it arrives out of nowhere.
