<unk>  is a medical condition in which the patient ingests abnormally large amounts of fluids by mouth. The word is made from the words poly meaning many and dipsia which means thirst. The fluid is usually water, though some people may think of alcohol because of the etymologically related term dipsomaniac, meaning an alcoholic.
