An opening with a job to do, and no interest in your opinion about it.

means An opening or hole, especially one in the body, through which something passes.

from From Latin orificium, a welding of os (mouth) and facere (to make) — literally 'mouth-making' or 'that which forms an opening.' It came into English through French in the medieval period, already carrying its dry, clinical precision — a word built for anatomy texts, not poetry.
