Abbreviation for Kitchen Police, military jargon for a duty which involves just about any menial task that needs to be done in a mess hall, from peeling potatoes to scrubbing pots and mopping floors. If you've never done it, try to imagine working as a busperson/dishwasher at a restaurant that serves breakfast, lunch, and dinner to 10,000 people a day. Probably the most universally reviled work detail the military has to offer, it is often used as punishment for misbehavior or for failing to volunteer for some slightly less miserable task, such as clearing landmines.
