A small hole dug in the ground to bury turds in, for when you can't find the john. Digging one of these "bunkers" is called Chunk Bunkering.
"If you go camping, remember to bring a little shovel so you can dig some "chunk bunkers" if you need to drop a dookie. Make sure you bury it though, or people might get pissed."
