The raygun first appeared as a wonder weapon in Call of Duty Zombies, introduced with World at War in 2008 and returning in later Black Ops games. Getting it from the mystery box became a famous moment of luck because of its power against waves of zombies. Clips of players shouting when they pull it spread through gaming videos and soundboards, with the double n spelling raygunn meme also used in searches. The clip now works on its own as a shorthand celebration for any lucky pull.
