Adventures in Wordmaking

I suggested on one list that we really needed a word expressing the deja vu feeling of having something happen in real life which previously happened in a book. Jerrie Atkins suggested "deja lu", which is apparently French for 'already read'.

Now (since this just happened at work) I think we need an expression for the smug feeling of having saved one's files just before the power went out. "Bluescreenfreude"? Or is that a Linux user's emotion? Hmm. Maybe "savin'freude" or "paranoidenfreude". Of course, we also need a word for the feeling of horror and frustration when one hasn't saved....
