While reading Scott Aaronson's Quantum Computing Since Democritus, I came across this passage:
But what if you want to apply quantum mechanics to the whole universe, including yourself? The answer, in the epistemic-type interpretations, is simply that you don’t ask that sort of question! Incidentally, that was Bohr’s all-time favorite philosophical move, his WWF piledriver: “You’re not allowed to ask such a question!”
While I can mostly infer what is meant here from context, to what does 'WWF piledriver' refer in this paragraph?
(Searching the web suggests something wrestling-related, but very little other than that, and there seems to be no pro-wrestling SE.)
