- A general chat term, used in many MMOs, which refers to the specific player action of charging in with no tactical plan. Gathering all possible aggro and then proceeding to try and survive the ensuing chaos. This action is often accompanied with a battle cry written in the chat window, or shouted over a headset, that states "LEEEEEEERRRROOOOY JEEEEENKIINSSSS".
This Term was originated based on an individual playing Warcraft who did this exact thing, leading to a brutal team wipe, after an extensive period of tactical planning by the player's team.
