poopee stop

The rest stops along highways that you only stop at when you are in desperate need to relieve yourself. They are scary, isolated and stink, so you’ve got to pee or poop really bad to use them. pee, poop, urinate, doo-doo, dump, take a leak, bowel movement, take a crap, drop a loaf, take a wiz, rest stop

I am not sure about this poopee stop, it looks like some shady stuff happens here.
