Greebo

A slightly popular term for Greebe Elevators, the contraction used extensively in TV and movies sponsored by Greebe Elevator Corporation in order to increase brand awareness. Despite the best efforts of both inventor Jonathan Greebe and the corporate marketing department, however, the general slang term for cars running along lengths of downline became simply elevators.

Modern usage, in shadowtalk: A person (or personoid) who attempts to invent or artificially introduce slang or shadowtalk terms.
