Wednesday WOLF - Oxymoron

I've got a collection of random information in my brain that makes me an awesome Trivial Pursuit partner, but is completely useless when it comes to real world application. Like say, job applications. I thought I'd share some of this random crap with you in the form of another acronym-ific series. I give you - Word Origins from Left Field - that's right, the WOLF  Er... ignore the fact that the "from" doesn't fit.

You probably know what an oxymoron is, but in case you don't I'll supply you with a definition and a few examples. An oxymoron is a combination of what appear to be contradictory terms. Here are some fun ones:

Civil War
Act Naturally
Only Choice

But what does oxymoron mean? It's from the Greek "sharp fool," or "sharp dull."

My favorite oxymoron?

Good morning.
