The sound comes from The Scary Maze Game, a Flash prank game created by Jeremy Winterrowd in 2004 that asked players to guide a dot through narrow mazes without touching the walls. On the final level the game suddenly replaced the maze with a screaming face, a trick that was filmed, shared and remixed across early YouTube and reaction channels. Because the setup looks harmless and the payoff is instant, the clip remains a shorthand for classic internet pranks and is still dropped into reaction videos, compilations and Halloween edits today.
