The idea that one's opponent in a debate is a butler who must provide all the proof, evidence, and sources one demands, regardless of relevance, burden of proof, or the reasonableness of the request. The butler fallacy treats the opponent as a servant obligated to serve whatever intellectual goods the demander wants, whenever they want them, in whatever form they specify. It's typically combined with moving the proofpost: each demand met with a new demand, each source rejected with a call for a different source. The goal is not to reach understanding but to establish dominance, to exhaust the opponent, to make debate so laborious that the opponent gives up. The butler fallacy is the signature move of bad-faith arguers who treat debate as a power game.
Example: "He treated her like a butler: 'Fetch me a source. No, not that one—a better one. No, not that one—a more recent one. No, not that one—a more authoritative one.' Butler fallacy in action: he'd appointed himself master and her servant, expected to be served endlessly, gave nothing in return."
