The Leeroy Jenkins meme originated from a 2005 World of Warcraft gameplay video uploaded by the guild 'Pals for Life.' While his guildmates meticulously calculated survival probabilities for the Upper Blackrock Spire, Ben Schulz's character, Leeroy, returned from getting chicken and charged into the dragon-filled room shouting his name, causing an immediate team wipe. Though later revealed to be a staged parody of rigid raid planning, the catchphrase became a global phenomenon, symbolizing impulsive action regardless of the consequences. Today, it is widely used across pop culture and social media to describe anyone who rushes headfirst into a situation without a plan.
