Burgess was the other possibility I thought of, even though I did know Tolkien (not "Tolkein"). He did create his own slang in A Clockwork Orange, which was essentially Anglicized Russian words. (The Russian word for "good," khoroshiy, was "horrorshow.") Carroll wasn't a bad guess either; he made up words in "Jabberwocky", a few of which, like "galumph", later became "real" words.
I'm definitely tired of all the Matt runaways; I got excited when Maureen built up a good score early on, but she fizzled out in DJ.
