Pastafarianism centers around veneration of the Flying Spaghetti Monster (FSM), a deity made of spaghetti and meatballs with two eyestalks. According to Pastafarian religious texts, the FSM created the universe after a night of revelry and is considered responsible for all aspects of existence.

Pastafarians may wear colanders on their heads as an expression of their faith. Pastafarianism encourages followers to employ rational and analytical methods to evaluate claims about the universe and serves as a vehicle for social commentary. Its adherents advocate for robust science education, and challenge religious privilege within public establishments, such as schools and workplaces.
