A parody religion or mock religion is a belief system that challenges the spiritual convictions of others, often through humor, satire, or burlesque (literary ridicule). Often constructed to achieve a specific purpose related to another belief system, a parody religion can be a parody of several religions, sects, gurus, cults, or new religious movements at the same time, or even a parody of no particular religion – instead parodying the concept of religious belief itself. Some parody religions emphasise having fun; the new faith may serve as a convenient excuse for pleasant social interaction among the like-minded.
One approach of parody religions aims to highlight deficiencies in particular pro-religious arguments – following the logic that if a given argument can also be used to support a clear parody, then the original argument is clearly flawed. This can be done through fictional religions found in many works of fiction - one example of this can be the Bokononism from the novel Cat's Cradle (1963) by Kurt Vonnegut. Another example of this is the Church of the Flying Spaghetti Monster, which parodies the demand for equal time employed by intelligent design and creationism.
