I dont knoe about Pig parties, but I have heard of a loser party, where you invite the not so popular fraternities and sororities on campus without letting on to what it was. This guy in a frat we alwasy hung with got up and told hi soanish class they were having one and what "loser orgs." he was inviting. He happen to mention ours and one of my new sisters was in his class. He didnt know she was an AGD though. Lets just say it wasnt pretty when we found out (we were far from one of the "loser" ones on campus). Anyways no one showed up to the party from any sorority or fraternity or GDI's. Just goes to show who the real losers are when you throw parties like that.
