When men urinate standing up, pee ricochets off the porcelain beyond the toilet or urinal. If you’ve used a urinal at the same time as someone standing next to you, his pee has splashed on you. If you share a bathroom with someone who stands when he pees, a fine layer of pee covers your bathroom floor. I f you use a urinal or stand when you use the toilet, pee splashes back on you.
