(noun) An imaginary friend for grown ups; commonly touted as being a supreme being responsible for the creation and continued maintenance of the universe. The identity and characteristics ascribed to God vary according to established doctrine and religious alignment. Most religious groups, however, agree that God hates gay people and frowns on the consumption of products containing pork. In a bizarre twist of fate God demands the faith of followers without the burden of evidence - however, this demand could not have been put forward without direct evidence that God exists (i.e. God must exist in order to issue commands to his followers).
Don't spank that monkey Billy, God is watching.
