mungtrain driver
A mungtrain driver is a highly skilled mungmaster who has reached such a high level of mungery that he/she is considered worthy of mass-munging.

The mungtrain driver must pilot the mungtrain around the world to mung people, regardless of age, sex, race or religeon. A mungtrain driver will conduct horrible acts upon corpses no matter what their condition may be. The mungtrain driver may also re-mung corpses. Mungtrain drivers have been known to create corpses from the living, usually by mistake or for pure entertainment.
Mike, Eddie, Aaron and Gary have just been promoted to mungtrain driver status.
