It was, I believe, Dan Collins at POWIP who first coined the term paraphrasing the famous Seinfeld line.
But it was this post by Mary Katherine Ham that brought me to do this:
Ham's post concludes:
If the Washington Post wants to lecture us on civility it should stick to instances of incivility that are a) actually incivil and b) actually documented, and stop making excuses for incivility, as long as it comes from Dems.
Or they could just continue yelling, "Civility NOW!" which of course they will.
We could call them Frank, but really they should remember what befell ...Kramer... in that episode.
Because the signs already exist that they're well on their way down that path.
