I learned a new word today! I didn't know that word, and my vocabulary is pretty good. Google tells me that it is from "The Hobbit," so I must have just guessed the meaning when I read the book. I think that J. R. R. Tolkien is intentionally being droll here. I believe he using a real word, and a very obscure one, as a joking substitute for bad language.

To confuse, confound or perplex An obscure word, to be sure. I would avoid using it.
