Slang for taking a shit. Used by backpackers and mountaineers to describe the deed with an optimistic, light-hearted tone for marking where they have been.
Ex 1:
Hey Bill, I'm going to go around that tree and print a map.
Ex 2:
"You all ready for the trip"
"Hell yeah, brother! I printed a big map this morning"
Ex 3:
"My son needs to print a map"
"The print room is down the hall and to the left"
