The University of No Football; Home of the Osprey; Also known as The University of North Florida. It is a relatively good school in Jacksonville, Florida that has NO FOOTBALL TEAM. Before attending this school students are blinded by the nice campus and good food so they don't realize there's NO FOOTBALL TEAM until it's too late.
Gator: " Hey, What school do you go to? "

Osprey: " UNF. "

Gator: " Damn. So... No hot football players? "

Osprey: " None at all. "
