Named after Office Space's Bill Lumburgh, this term applies to anyone in a useless job who's boss makes them feel important-- like coming in on the weekends, or getting dumped with a bunch of reports that are alledgely important, but are really the boss's work that he/she doesn't know how to do.
John: "Hey Bob, you going out with the rest of us Saturday night?"
Bob: "Nah, I can't. I've got these reports to do."
John: "How did you get lumburghed into that? That sucks. Screw your boss, get your drinking shoes on."
