Squick

I happened to catch some of NPR's On the Media on Sunday, and they had a little piece about new words coming into the language.  The Word of the Year is "podcast", which really doesn't strike me as terribly interesting, but one of the runner up words they discussed was "squick".  The dictionary person said something as to how she couldn't talk about the etymology of "squick" on the radio, and just as she implied what it was she couldn't talk about, I drove under a power line and could only hear static.  (To digress randomly, the following program, Media Matters, included a mention of how the move to introduce digital broadcast radio, the solution to AM radio that goes away when you drive under a power line, is being taken over by greedy corporate interests pushing a proprietary technology that broadcasters would have to pay a lot of money to license, and how basically Clear Channel is basically trying to use it to squeeze its stranglehold on broadcast radio until nothing is left but their profit margin, and there was much wailing and gnashing of teeth.  Digression ends.)

So, does anyone more enlightened than I am know where the word "squick" comes from?  It seems like a pretty good word to me, since it describes a pretty specific emotional reaction that I find hard to express with other words.
