Pretty much everybody has joke placenames, I imagine, where a name is twisted into a negative. People from Indianapolis call it India-No-Place, and our corespondent formerly from Purdue calls that place Purdon't (or l'université perdue) and the town West Laffalot.
Here in Wisconsin, I've heard people call Mount Horeb Mountain Horrible (which doesn't quite work for it, since it's a very pleasant place, and I'd love to be able to visit the Grumpy Troll, their brew pub, more regularly.) Yesterday I learned LaCrotch for LaCrosse and the marvelous Crappleton for Appleton. The last one is downright Simpsonian, especially given the name of Bart's teacher. Of course these show up all over the web, at least most of them, and there's a real Mount Horrible, in New South Wales I think, though I've never climbed it.
