Leeroy Jenkins comes from a 2005 World of Warcraft video by the guild Pals for Life, in which player Ben Schulz, as Leeroy, shouts his name and charges into a dungeon while his group is still planning. The clip spread rapidly across early video sites and forums and became one of gaming's first viral memes. Blizzard later honoured it inside World of Warcraft and Hearthstone, and the name became shorthand for a reckless charge. Creators still use the shout today because it instantly tells an audience that a plan is about to be ignored.
