Answer 3

p**p deck is where you go p**p.

I was talking to some guy that was on a military boat and he said that the bathrooms did not work.

so they made everyone go on a spot on the deck, then washed it off with a high pressure hose.

don't know if he was making it up or not, but he seemed serious and its a funny reason that it should be named after something so practical.
