A person who is pathologically contrary to everything that is said to him/her. Will argue black is white until they are blue...no green...no red in the face. Even if you agree with them they will rise up in opposition. Political life is the perfect arena for this kind of nonsense.
It's wonderful that Barack Obhama has become the first black president of the USA
He's not black, he's white!
Oh, you're such a disagreement junkie
