First used in the early 1970's as a all-purpose sobriquet for conservativepoliticians 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.
Stupid warmongering pigfucker freeps don't understand that neo-con policy in Iraq will cost them any hope for a prosperous future.
Someone who supports the police. For instance, a politician who passes laws demanded by the police and thereby destroys civil liberties, and anti-"crime" bigots who go along with any repressive proposal which has even minimal porcine endorsement.
Also someone who literally sleeps with, or who enjoys close personal relations with police officers.
