STFU

The esteemed school known as St. Francis University. Named after the valiant Catholic priest Saint Arthur Francis, STFU is dedicated to providing their students a quality, yet spiritual education. In addition to the superb education offered at STFU, they are also known for their outstanding basketball team. Their mascot is the fabled Unicorn, as students can be seen all around the campus holding a hand to their forehead and pronouncing "UNICORNS!!!!" to the rest of the world.

1. "S--T--F--U--S-T-F-U-UNICORNS FIGHT!!!"
2. BAM!!! I just Unicorn stabbed you with my horn.
3. "Oh yeah I remember STFU, they had a good basketball team." - Mr. OL
