Mania

A bipolar mood disorder characterized by flamboyance and expansiveness. A person experiencing a manic episode may go on shopping sprees, engage in sexually promiscuous behaviour, take on numerous, unrealistic work commitments, brag, and dominate others socially.

Extreme or prolonged cases of mania are considered bona fide psychotic states, implying that the person is experiencing a break with reality.
