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.

The god of the Church of the Flying Spaghetti Monster, which is not a conspiracy to create a holocaust of religious people, unlike what some definitions would like you to think.
His noodly appendage having shown me the one true faith... Well, besides Buddhism, Islam, Obamaism, and even Christianity, and FSM. Oh, I said that already.

The almighty Flying Spaghetti Monster. Under the religion of Pastafarian, you worship this almighty deity.
Once i found the FSM, i was saved. His almighty sauciness engulfed me, and i was at peace with the world.

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.
