T.N.M.D.

Abbreviated term for "that's not my department" used to describe an annoyingly indifferent office staff member not willing to do their bloody job.

Tom: "I called Michelle in payroll to tell her that I got shorted a day's pay on my pay check and she told me to take it up with my supervisor! I mean why the hell can't she call him?
Bill: I hear ya dude! Jeezus she's so T.N.M.D. !!
