Field dressing is the act of taking another person's backpack and removing all of the contents. The contents then must be laid out orderly. While field dressing a backpack, the field dresser must go about it like an educational program on wilderness survival, an Australian accent is advised. The owner of the backpack in question must be kept unaware so stealth is key.
-What's going on?
-Oh, John's backpack is being field dressed.
