An oxymoron (plural oxymorons or, more rarely, oxymora) is a figure of speech that combines two normally contradictory terms. Oxymoron is a loanword from Greek oxy ("sharp" or "pointed") and moros ("dull"). Thus the word oxymoron is itself an oxymoron.
I think this pretty much sums me up in a single word. Or should it be a defining characteristic either way its me.
