When an animal plops it's leaking anus down on your floor, desk, kitchen table, or other surface you wish it hadn't (pretty much every surface) and leaves a slimy excretion from it's anal glands.
My cat pulled a Chester Cheetah style prank on me as it sat, stepped, and repeated all the way across my desk leaving an anal juice stamp at each "sit" interval.
