Let me see if I can beat you guys the punch and keep from getting clobbered:

Although it didn't appear in my quick search of an evidently poor online dictionary, ober (but not Ober), in the sense the original question suggested, means "upper." That's where you get Ober the waiter and all that stuff. The funny thing is, it's smack in the middle of a name I suggested for a racing horse on another board.

Still standing,
