She has a tendency to take whatever a person says and (twists, sours, distorts, inflames as evil) to make some one look bad or way worse than they really are.
She would be having a conversation with another in a family setting. All the rest understands what the other is saying, but when "she" hears it, it is evident by her response that she was taking it as a negative about herself, or something she likes, which it was not.
Then she will single a phrase out from what was said and answer, obviously from a distorted perception, then embellish the distortion coming out with an inflamed, corrupted and evil twist, to sour everyone else's view of the person she is arguing with, to make herself seem good.
What would be a term to refer to such a way of communicating? Verb for the action, or adjective to describe it or term for such a Disorder?
