Oxymoronic

OXYMORON DEFINED
A figure of speech by which a locution produces an incongruous, seemingly self-contradictory effect, as in “cruel kindness” or “to make haste slowly or "jumbo shrimp" or "pretty ugly".”

Rebekah got a CD in the post entitled "Essential Bluegrass." Seemed to me one of the best examples of an Oxymoron I have ever heard.
George Wills - generally a right-wing dolt - did however get it right when he pointed out that "domestic cat" was spot on as an oxymoron.
