The clip comes from a 2005 World of Warcraft video by the guild Pals for Life, where player Ben Schulz returned from being away, shouted his character name Leeroy Jenkins and rushed into Upper Blackrock Spire. The staged raid wipe spread across forums and early video sites long before modern meme pages, turning the name into shorthand for reckless confidence. Blizzard later added references to Leeroy in World of Warcraft itself, and the shout remains a standard gaming soundboard staple for doomed charges.
