Designation as a Sub-Human Piece Of Shit, applied by medical personnel in hospitals to their less-than-desirable patients.
In an article published in Values, Ethics, and Health Care, 5 (1980), pp. 226-228, Harold Schwartz attests that S.H.P.O.S. is "an acronym for 'subhuman piece of shit' applied by medical interns and residents to their most unpleasant and uncooperative patients."
