MOCK (SOMETHING) UP

as used here, it simply means "create (something)." In Scientology, the word mock-up is used to mean, in essence, something which a person mocks up himself. A mock-up is more than a mental picture; it is a self-created object which exists as itself or symbolizes some object in the physical universe. The term was derived from the World War II phrase for miniature models that were constructed to symbolize weapons (airplanes, ships, artillery, etc.) or areas of attack (hills, rivers, buildings, etc.) for use in planning a battle. —Melbourne Congress Approved Glossary (2.4.92)
