R2-45 is Scientology slang for murder or suicide by gun. Scientology founder L. Ron Hubbard described it as "an enormously effective process for exteriorization but its use is frowned upon by this society at this time".[1] In Scientology doctrine, exteriorization refers to the separation of the thetan (soul) from the body, a phenomenon which Hubbard asserts can be achieved through Scientology auditing. R2-45 is said to be a process by which exteriorization could be produced by shooting a person in the head with a .45 caliber pistol. This literal meaning is acknowledged by the Church of Scientology, although they deny that it is meant seriously.[2]
