The line comes from World of Warcraft, where Illidan Stormrage delivers it during his boss encounter in the Black Temple raid from The Burning Crusade expansion. Players heard it at the start of one of the game's most famous fights, and clips of the encounter quickly spread through gaming forums and YouTube. It became a shorthand warning in memes, edits and streams, used whenever someone is about to face an overwhelming opponent. Its theatrical delivery and association with a legendary raid boss have kept it recognisable to gamers years after its debut.
