A mentor-worthy person in one's life whose example has been regrettably ignored. A could-have-been/should-have-been mentor. Someone you meant to follow as your mentor.
My father was my meantor. He was a worthy man who led a good life. I, on the other hand, have led a thoroughly slovenly, worthless life and have ignored my father's example at every turn.
