Leeroy Jenkins became a gaming legend after a 2005 World of Warcraft video showed a player shouting his character's name and charging into a dragon-filled room while his raid group was still planning. The reckless rush wiped the group, but the clip spread through forums and video sites and became shorthand for acting without thinking. It has since appeared in countless edits, streams and memes, and remains popular because the moment is instantly recognisable and easy to drop into any doomed plan.
