Accidently having an anal evacuation in a urinal, then either picking up the poop and hiding it, or leaving the area and pretending that nothing ever happened...
Luigi: " Jim pulled a Urinal Poop Swoop the other day, at the office, and left a big dukey in one of the urinals!"

Peter: " Yeh, Tom did that the other day, only he hided the poop...When my boss found Toms poop in his desk, he sacked him!"
