Histrionic Personality Disorder.
Histrionic personality disorder (HPD) is defined by the American Psychiatric Association as a personality disorder characterized by a pattern of excessive emotionality and attention-seeking, including an excessive need for approval and inappropriate seductiveness, usually beginning in early adulthood. These individuals are lively, dramatic, enthusiastic, and flirtatious. They may be inappropriately sexually provocative, express strong emotions with an impressionistic style, and be easily influenced by others.
