This is the perfect way to describe it.
If you have it to lose, either in body fat or water, a single pound is literally nothing at all.
If you are already dry as a bone, and your ribs are visible, you are going to seriously diminish yourself shaving it. Seriously. I say a junior lightweight spitting into a trash can once before a weigh in desperately trying to get that last bit of moisture out. He was a 17 year old amateur. It was horrifying.
