The line comes from The Elder Scrolls IV: Oblivion, released by Bethesda in 2006, where Dremora warriors serving the Daedric Prince Mehrunes Dagon shout it during combat. Dremora Lords, the toughest of these red-skinned Daedra, bark taunts like this before attacking the player at Oblivion gates. It belongs to the same family of game voice lines as Enemy Spotted and the bomb has been planted callout, and it became a favorite in Elder Scrolls meme compilations. Its mix of melodrama and menace keeps it quotable for boss entrances and betrayal clips.
