Thunderation

I just looked up the word "thunderation" on dictionary.com expecting to find nothing but instead found this:

an exclamation of surprise or petulance.

Hmmm...and here I was thinking I'd made the word up. I've made up a few -- like angravation (a combination of "angry" and "aggravation") or nooch (what a dog does with his mouth to other parts of his body).

This was supposed to be about rain and thunder -- which we've had a lot of down here in these parts for the last couple of days -- I love it -- maybe I'm weird but I prefer rainy days to almost any other.

But I think the question now is -- have you made up any words -- words which other people now use because they've heard you use them?
