A loose group of plebs here in the UK. The acronym stands for Union of Arrogant Fascists. Comprises chinless inadequates, illegal immigrants and uptight feminists of the Bull-dyke variety.

University of Arkansas Fort Smith. Quite possibly the poorest excuse for a college in the nation. It is a glorified community college that instead of expanding parking and such they want to build more dorms for some reason. The teachers there are as liberal as they come and spout off pathetic lines like, "People who don't abort children with Down's Syndrome are irresponsible." I'm not kidding either...
Child: Should I go to UAFS or live under the bridge?
Parent: Neither, they're about the same.
