You are probably wondering what the heck I am referring to! A Pakistani once let it slip to me there is a gang called P.I.G.S = The "Pakistani International Gang Sta(r)s"! Ever heard of them or heard mention of them?
Found this http://children.webmd.com/vaccines/news/20100322/pig-virus-found-in-gsk-rotavirus-vaccine while doing a quick search for P.I.G.S. Maybe a small group of teenager or just a hoax.
