Never heard it, ita. Same thing as tailbone, I guess?
Robin, I'm not sure any of the watch lists are public. My recollection is you mostly find out you're on the TSA one when you get booted off a plane. And I highly doubt we even know about all of them.
I've heard both sit bone and seat bone -- not everywhere, but in enough contexts that people seem to get what's being talked about.
This weekend, I'm scoping out a town I may decide to move to, doing laundry, and possibly listing stuff on eBay. Also, napping.
I have heard of the "sit bone" but I didn't know there really was one.
cereal: My understanding of watch lists matches Brenda's. Nobody can check them, and you don't know until you're spanked. Cocksuckers.
I've only heard "sit bone" used in yoga classes.
Oh my god that bike is incredible
That bike needs to be in the next Batman movie.
I looked at someone funny for using the term "sit bone" and he defended himself by saying it was the real term. I grant, rolls off the tongue a hell of a lot easier than ischial tuberosity. But it's nowhere near as fun to type.
To be fair, I don't think I have ever heard the term "ischial tuberosity" at all.
On Saturday I'll be putting my first floor back together. We had to box up breakables and a gazillion CDs because we had most of the flooring on our first floor replaced today. [Link].
On Sunday I'll be matching up applicants with Labrador retrievers.
DH is on a road trip this weekend to see ballgames in Chicago and Milwaukee.
Robin, it depends on what you mean by a watch list. There are lists of SDNs (Specially Designated Nationals) that are both individuals and entities who have been declared as or being investigated for funding/working with terrorists: [link]
