The line comes from The Elder Scrolls IV: Oblivion, released by Bethesda in 2006, where Imperial Guards use generic combat barks during fights with the player. Oblivion's guards became a lasting meme source because of their serious delivery and repetitive dialogue, and short clips of their lines spread widely on soundboards and in gaming edits. This particular bark survived as a confident taunt, reused whenever a player wants to pretend an early loss was only a warm up round.
