Call of Duty: World at War, released in 2008, introduced the cooperative Zombies mode that later became a defining part of the series, with each round beginning with this unsettling laugh as the undead threat reset and intensified. Clips of the mode spread through gameplay videos and fan soundboards, where players recognised the cue immediately even without seeing the game. It remains popular today because it works as shorthand for a horror round starting, connecting modern edits back to one of the earliest and most influential zombie survival modes.
