Irrationally irascible

Always eager to psychoanalyze everybody, mainly because he's been in therapy for most of his life, the angry man is easily provoked, hot-tempered, and prone to ugly contorsions of the face when he disturbingly pretends to withhold his choleric humor. The most theatrical version will have him holding his irate head with both hands, as if pained by the idiocy of his victims. He alternates between spinning tales, senile ire, boastful rage, and unsubtle bullying. No wonder he has no true friends.
