Stands for Flying Spaghetti Mosnter. The Flying Spaghetti and Meatball monster is believed to be the one who created the world, by Pastafarianists. Initially Pastafarianism was created to protest the Kansas State School Board's decision to teach "Intelligent Design" in schools, one man invented a parody religion, Pastafarianism. Pastafarianists believe the FSM created the world. The FSM and concept of Pastafarianism eventually became an actual religion, one with a bible and church. Unlike what some people may believe, the FSM was not created by atheists to mock the concept of religion.
FSM, meaning Fuck Starrs Mill, is a term to describe the hatred felt by the students of Mcintosh High School to the students of their rival team, Starrs Mill High School, both in Peachtree City, Ga. The Starrs Mill Panthers are entirely inferior in every way to the Mcintosh Chiefs.
Chief: That buzzer beater at the basketball game was amazing! FSM!
