A term used between 2 individuals when travelling through an area which
you wouldn't normally traverse because it is frequented by a bunch of horrible individuals who would not think twice about shagging you up the arse!
Taken from the disturbing film
Deliverance, where Burt Reynolds and friends get chased by a bunch of
hillbillies in the woods, who want to shag Ned Beatty up the poop-shoot!
