The act of sneaking into someone else's room, dropping a payload in their toilet, not flushing, and then leaving a note signed 'Pooping Tom' on the toilet seat. Usually occurs in college residence halls.

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?"

Guy1: >:3
Usually right after lunch break in a factory, employees will fill up the six stalls in the men's room and engage in team pooping. They will talk about useless sports news while they pound one out. The medley of aroma is strangling and will make your eyes burn. If you hold your nose, you will taste it. Truly makes you wish you would have stayed in school.
"Look at Jeremy. He just experienced his first team pooping. Either you love it or you hate it. I think he hates it."
