The Tale of Leeroy Jenkins

Leeroy Jenkins, sometimes misspelled Leroy Jenkins and often elongated with numerous additional letters, is an Internet phenomenon named for a player character created by Ben Schulz inBlizzard Entertainment's MMORPG, World of Warcraft. The character became popular due to a video of the game that circulated around theInternet. The phenomenon has since spread beyond the boundaries of the gaming community into other online and mainstream media.
The video was released by the World of Warcraftplayer guild "PALS
FOR LIFE". It features a group of players discussing a detailed battle
strategy for the next encounter while one of their party members,
Leeroy, is away from his computer. Their plan is ruined when Leeroy
returns and, ignorant of the strategy, immediately charges headlong into
battle shouting his own name in a stylized battle cry. His companions
rush to help, but Leeroy's actions ruin the meticulous plan, and all of
the group members are killed.
The Internet phenomenon started with the release of the video clip to the World of Warcraft game forum in a thread titled "UBRS (vid) ROOKERY OVERPOWERED! blue please.", which jokingly presented the video in a serious context.^[1] The
thread requested that other players provide help with strategy and that
Blizzard reduce the difficulty of the encounter. The video spread as
an internet meme, and Leeroy's response to the other players' chastisements, "at least I have chicken", was also much parodied.
