Additional meaning

Lynn read me an item on Facebook. It seems that a couple were driving along a back country road on a cold day in the north.  She was overtaken by the need to urinate. He pulled over, nobody was coming.  She did the necessary work in the road, leaning against the bumper of the truck.  Very much relieved, she discovered she couldn't arrange her clothes properly because the leaning action had frozen her skin to the bumper.  A little tug wasn't doing it.  She wanted to avoid a bad wound.  What to do?

He realized he could free her using his own urine stream and explained the possibility. She approved the plan and it worked.

One commentator observed that their experience gave a new meaning to the phrase "being pissed off."
