The phrase comes from South Park, where Eric Cartman adopts it while pretending to be an authority figure, despite being a schoolchild with no real power. The mispronunciation of authority as authoritah became part of the joke and helped the line stick long after the original episode. It spread through early soundboards, YouTube compilations and meme edits, and later found a second life on TikTok and in gaming streams. It endures because it instantly frames any petty power grab as comedy.
