Really?
I first read it in The God Delusion (ha! sorry!) then I saw it in Newsweek (?), and if I'm remembering correctly it was in Next (book).
I had NEVER heard it before previously and it was so strange to see it pop up again and again but for some reason that seems to happen to me with new words. Weird.
I don't think I could ever use this word in a sentence, though, without sounding like a complete idiot (as opposed to the highly intelligent person I come across as now, haha).
Thanks for the call btw, you are so sweet and helpful!
