A CORRECTION: While I do say "fact check your ass" from time to time, it's Ken Layne who coined the term. This article from The Guardian gives the impression that the term is uniquely mine, which it isn't -- either by origination or by frequency of use.
Hey, I just "fact-checked the ass" of an article over the phrase "fact-checking your ass." I think that should get me the recursive metablogging medal of the day. Or at least a good seed in the recursive metablogging tournament.
