The act of adding a specific feature onto a theoretically finished contraption or building to stop Grian from tampering with it, which may result in said contraption/building being destroyed in a half a second.
Grian-Proofing may also be used to classify some kind of lock on an object that stops it from being used by normal people that don't have the key.
Guy1: "OK, I think I've finished this massive redstone-only item filter."
Guy2: "Did you Grian-Proof it?"
Guy1: "Oh yeah... Would adding a misc. item bin be sufficient Grian-Proofing?"
Guy2: "Make sure he can't get the items back"
Guy1: >:3
You get a free pass professional courtesy when you get stopped by the cops for a traffic violation because you are an off-duty or retired cop and have a cop ID to flash when the officer requests your drivers license.
Cop's wives and girlfriends are also ticket proof and so are off-duty firefighters.
Nobody is ticket proof with the Arizona DPS, and with some California Highway Patrol officers. Don't count on your police ID to help you much if your breath smells like a brewery.
That trooper said he had me clocked at 95, good thing I'm ticketproof or that would have been one hell of an expensive ticket.
My skin is thick, cause I be up in the mix of action,
If I'm not at home, puffin lye relaxin,
New York got a nigga depressed,
So I wear a slug proof underneath my Guess
