What is "ooblick"?

[Thorin]

My wife picked up The Geek Handbook at the library a few days ago.  It's a book for the commoner to understand the geek in their life.  Apparently, there's a "Geek Quiz".  One of the questions is, "What is ooblick?"



So how many of you know?



The stuff is described here and here...



And no, I didn't know what it was.  Guess I'm not an uber-geek.
