not even!

Not even! Is a slang expression often used as a state of denial where you are strongly denying something which has just been said to you. Often times, it is a comment or observation that someone has made about you or someone you know very well and because you very much disagree with their assessment, you will say not even! It is typically spoken by adolescents but been known to be uttered by adults who choose to use slang in their vocabulary.
