FYI, these are called oxymorons, where one word contradicts the other (like LargeShrimp or AdultChild, etc). I run across them occasionally and throw them on my list (see Bannen's in sig). A lot of fun. Yours is a neat one. I like it, but don't need one now.
Yours is useable and the price is right, so hope someone scoops it up.
Good luck.
