a group of players discussing a detailed battle strategy for their next encounter while Leeroy is away from his computer, fixing a meal. This risky plan is needed specifically to help Leeroy, yet it 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 massacred. Wikipedia
