"Leroy Jenkins" is a popular internet meme that originated from a video of a group of players in the game World of Warcraft. In the video, a player named Leroy Jenkins charges into battle without coordinating with his team, leading to chaos and their defeat. His enthusiastic shout of his own name became iconic, symbolizing impulsive and reckless behavior in gaming. The meme has since transcended gaming culture, representing moments where individuals act without thinking or disregard plans. Leroy Jenkins has become a symbol of spontaneity and the humorous side of teamwork failures in various contexts beyond just World of Warcraft.
