the male equivalent of a "psycho chick/bitch." basically a guy who seems sincere, emotionally available, and affectionate until you disagree with him or catch him cheating, at which point he morphs into a defensive, mean-spirited, controlling jerk and tries to put the blame for HIS dishonest behavior on you.
I couldn't believe Derick turned out to be a Psycho Dick! He went from a dream boyfriend to an abusive jerk when his ex showed up in town.
