Shettle

Used by one who recently "claimed" a toilet as their own. Commonly used by germaphobe-like people who hate having friends use their toilet. Has similar attributes to that of the territory disputes of western settlers in the 1800s or that of a dog that isnt neutered and has to mark its territory every god damn place.

Greg- "Hey Brah, I really gotta take a shit, this turd's at the drive-thru window!"

Charlie- "Nah man, I already shettled it."
