Short for "The State University of New York at Buffalo". Is a two campus school where the professors often times lack English speaking skills and classes in mathematics or other departments could and should also recieve credit towards the foreign language requirement. The UB student body is composed of a heavy percentage of Asians and Jewish, dick-loving whores from Long Island (pronounced "Lawn-Guy-Land"). Also known as "Jew-B" (in reference to the heavy Long Island population).
