# psycho short for psychotic. A person characterized by or afflicted with psychosis. an individual who is out of contact to a thorough extent with his present time environment and who does not compute into the future. He may be an acute psychotic wherein he becomes psychotic for only a few minutes at a time and only occasionally in certain environments (as in rages or apathies) or he may be a chronic psychotic, or in a continual disconnection with the future and present. Psychotics who are dramatically harmful to others are considered dangerous enough to be put away. Psychotics who are harmful on a less dramatic basis are no less harmful to their environment and are no less psychotic. See psychotic in this glossary.
