Jumpscare roars became a staple of online horror editing as short-form video and game streams rewarded instant reactions over slow build-up. Creators lift the format from haunted house attractions, horror films and monster games, where a quiet scene is broken by a loud creature vocalisation. This type of clip spread through soundboards, meme pages and editing packs because it needs no context to work and can be dropped into almost any timeline. It remains popular for Halloween content, Five Nights at Freddy's fan edits and prank compilations where the reaction matters more than the scare itself.
