Sated might could work for 'cain't get no fuller,' depending on circumstances. Maybe evacuated for '…no emptier.' Ok, but--I think shellb is looking for a term for the words which, if I may perhaps put it a different way, either are or aren't. (A nice, comfortable concept, I might add! Either black or white--no darned ol' shades of gray.) So, perhaps without arguing about my specific and no doubt arguable examples, I will try, besides
empty:
pregnant,
and broken. Tsuwm?

Shellb, please post if my assumption/examples are not what you meant.
