Leeroy Jenkins began as a 2005 World of Warcraft gameplay video in which a player, after his group spent minutes planning a careful attack, shouted his character's name and charged alone into a crowded room. The clip spread quickly across gaming forums and early video sites, becoming one of the first widely shared gaming memes. Blizzard later referenced the moment inside World of Warcraft itself, and the name became shorthand for reckless bravery. It remains popular because the setup is instantly recognisable to gamers and newcomers alike, even without knowing the original raid.
