I've written before about the placename element -stan and its use. It's not only for playing on American ignorance of Central Asia, but gets extended to the U.S., as noted earlier: Dumbfuckistan = 'parts of the United States that voted for Bush'.
A couple of times, most recently this morning on the radio, I've heard Berserkistan, basically meaning, as far as I can tell, the transparent 'crazy land'. This cracks me up for a presumably unintended reason: I can't hear that joke without thinking of it as the land of the original guys called berserkr, the warrior cult — not the metal band. That's a stamp you don't want in your passport.
