A special kind of Polyamorist is a Serial Polyamorist. They go though relationships and spread STD's much faster than your standard Monogamist. Serial Polyamorists are demographically spreading STD's faster than humans are bearing children. The only thing on earth that spreads faster than Polyamorous STD's are the legs of a Serial Polyamorous woman who has stockholm syndrome and is hypnotized by the sweet calming words of an ego-stroking anarchist. A complete case study of this phenomena relating to Charles Manson can be found here.
