A parody religion or mock religion is a parody of a religion, sect or cult. A parody religion can be a parody of several religions, sects, gurus and cults at the same time. Or, it can be a parody of no particular religion, instead parodying the concept of religious belief. In some parody religions the emphasis is on making fun and being a convenient excuse for pleasant social interaction among like-minded, e.g. the Church of the SubGenius. Other parody religions target a specific religion, sect, cult, or new religious movement.

One approach to parody religion aims to highlight deficiencies in particular pro-religious arguments — the thinking being that if a given argument can also be used to support a clear parody, then the original argument is clearly flawed. An example of this is the Flying Spaghetti Monster, which parodies the equal time argument employed by intelligent design Creationism.

Several religions that are classified as parody religions have a number of relatively serious followers who embrace the perceived absurdity of these religions as spiritually significant, a decidedly post-modern approach to religion. For instance, in Discordianism, it may be hard to tell if even these "serious" followers are not just taking part in an even bigger joke. This joke, in turn, may be part of a greater path to enlightenment, and so on ad infinitum.

Rebecca Renee Black (born June 21, 1997) is an American pop singer and dancer who gained extensive media attention with the 2011 single "Friday". Her mother paid $4,000 to have the single and an accompanying music video put out as a vanity release through the record label ARK Music Factory. The song was co-written and produced by Clarence Jey and Patrice Wilson of Ark Music Factory. After the video went viral on YouTube and other social media sites, "Friday" was derided by many music critics and viewers, who dubbed it "the worst song ever." The music video received around 167 million views, causing Black to gain international attention as a "viral star", before being removed from the site on June 16. Black re-uploaded it in her own channel three months later.

Rebecca Black was born on June 21, 1997, in Irvine, California. She is the daughter of John Jeffery Black and Georgina Marquez Kelly, both veterinarians. She is of Mexican, Spanish, Italian, English, and Polish descent. An honor student, Black studied dance, auditioned for school shows, attended music summer camps, and began singing publicly in 2008 after joining the patriotic group Celebration USA.^{[citation needed]} In 2011 Black left public school in favor of homeschooling, both in response to constant verbal bullying at school and in order to focus more of her time on her career. Black later said that her main reason for the move to homeschooling was more for career reasons rather than the bullying.
