(Scientology slang) one's
body and his presentation of it. In
Scientology, the
word mock-up is used to mean, in essence, something which a person makes up himself. It is something a being creates, which he puts up and says is there. 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.
