A person, or group of people, that really have no value to hang around with or be associated with. Either they are hideous, or they
do things that really nobody should want to be a part of. (Taken literally, if someone was a "shit-fucker", or gay, this is something nobody would want to be a part of.)
Arose from the
distaste for a certain
sorority filled with terribly ugly and fat girls which nobody should want to join because they are rather uncool.
Example:
I can't believe they didn't give her a
bid, because shes slutty. They need girls like her. That
sorority is full of a bunch of
fat and ugly bitches. They are a complete bunch of shit-fuckers.
