I certainly don't claim to have coined it, though I couldn't tell you where I saw it. One thing about reading a lot on the internets - blogs, messages boards, comments sections - is that a lot of bits float through your mind and by the time you write about it you forget where it came from.
Maybe if someone on the internet made this story up completely the Washington Post would spend more time covering it. They aren't much interested in the non-fiction version.
