Susto is Portuguese for scare or fright, and estourado describes audio pushed so loud it distorts, a style popular in Brazilian funk edits online. Clips like this spread through short-form video and meme soundboards, where creators reuse the same blown-out beat as a ready-made jumpscare punchline. Instead of coming from a film or show, its identity is tied to that exaggerated loudness and the sudden drop itself. It remains popular because a single hit can turn an ordinary scene into a joke without needing any explanation or dialogue.
