Dracula has been a cultural shorthand for vampires since Bram Stoker created the character in 1897, and his theatrical laugh was popularised by decades of stage plays, films and cartoons that turned the count into a campy villain. Online, the laugh detached from any single performance and became a reusable reaction sound for Halloween content, horror memes and villain edits. It survives because it needs no explanation: a few seconds of that deep, mocking cackle instantly tells viewers someone evil, mischievous or victorious is on screen.
