Inedible as in anything that isn’t food (ranging from something that would be dangerous, like glass, poisonous plants, or uranium, to something that is safe to eat but unpleasant with no nutritional value, like cardboard.) Eating the thing will be safe and painless.
An aircraft carrier, including all the seamen. I’m famished.
Start with the semen, you’ll be full before you get to the food rations.
