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.

To be used in the context of Minecraft

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

Get the Grian-Proofing mug.
To create a machine, contraption or building and add specific features that would prevent a Grian from wanting to interact with it, to stop him from breaking it in a fraction of a second, or to keep him not wanting to use it.

Must be used in the context of Minecraft.

Grian-Proofing may also be done with specific items but trapping them with him knowing - anything would prevent a wild Grian from completely obliterating what you've just spent half your life on is a viable Grian-Proofing measure.
Guy1: "OK, I think I've nearly finished creating this massive item filter for redstone-only items"
Guy2: "Wait, remember to add a seperate item bin onto the end, that should Grian-proof it well enough to stop it from clogging,"
Guy1: "Oh yeah... I forgot about Grian-Proofing."

Making a machine or contraption in a way that even Grian or someone who doesn't know what they're doing can't break it by spamming input buttons or leavers, typically in Minecraft.
