In 2005, a World of Warcraft raid group planned their attack and calculated a 32.33% survival chance.
Leeroy Jenkins had stepped away to reheat chicken. He returned, ignored the plan, yelled his name, charged in alone, and wiped the group.
Video quotes: “Leeroy, you are just stupid as hell.” “At least I have chicken.”
The clip was a staged reenactment by the PALS FOR LIFE guild. It spread widely online, got referenced in South Park, How I Met Your Mother, and a military journal, and Blizzard added Leeroy Jenkins as an NPC.
The name became slang for reckless actions that ruin plans.
The real player, Ben Schulz, repairs industrial lighting.
