The highest of all proofs. An object so strong it cannot be undone or marred by anything (i.e. fire, power tools, teeth, natural disasters), even proof.
No single one of their hair-brain schemes was proofproof.

(Adj.) a person that is immune from proof and will not consider evidence, change his or her perspective, or reconsider an idea. The same way that a waterproof boat is protected from water, a proofproof person is protected from proof.

(Adj.) a theory that is constructed in such a way as to be impossible to disprove, ie it is non-falsifiable.
“Wow, Sean Hannity just admitted that he will not believe that Russia colluded with the Trump campaign no matter how much proof there is. He is proofproof.”

Immanuel Kant’s deontological theory of rights is based on the supposed inherency of worth or value to certain ideas. So no matter how much evidence or logic you muster, it won’t change. It’s a proofproof theory.”
