n. - A person that lacks intellegence and/or common sense, to the point of seeming to be mentally retarded, who is not actually a retard, thus making it socially acceptable to smack them as needed. This condition is currently commonly caused by exposure to online chat rooms, and was previously mostly caused by smack (heroin, not cocaine as suggested by other definitions, and part of the origin of the term, if not part of the current evolution.)
