The line comes from Halo Wars, the 2009 real-time strategy game set in the Halo universe, where Sangheili warriors, also known as Elites, fight for the Covenant. Spoken as a battle cry against enemies judged heretical, it was later lifted from gameplay audio and shared on soundboards, where its theatrical anger made it easy to reuse outside the game. It endures because the meaning needs no context: the speaker is not debating, but ordering something offensive removed, which fits reaction videos, gaming edits and jokes about unwanted ideas.
