First used in the early 1970's as a all-purpose sobriquet for
conservative politicians by Dr. Hunter S. Thompson. Recently, the meaning of 'pigfucker' has changed to exclude the actual politicians, focusing instead only on the ill-educated, ignorant or mentally-challenged supporters of explicitly neo-conservative politics. In
contemporary usage, therefore, neither Schwartzenegger nor his supporters would be'pigfuckers', but any trailer-dwelling Anne Coulter spouting asshat would be.
