P and W stands for Piss and Walk. Commonly, when pissing in public you do not wish to draw suspicion by facing a wall for a minute. Or get left behind by the group. So instead, you piss while walking. Commonly needed in the city, especially after drinking.
-Should only be done at night.
-Male maneuver only.
