hangover (n.)

also hang-over, 1894, "a survival, a thing left over from before," from hang (v.) + over. Meaning "after-effect of excessive drinking" is attested by 1902, American English, on notion of something left over from the night before. As an adjective, in reference to a person, overhung (1964) has been used but is rare; that word meaning generally "placed so as to project or jut out" (1708).
