The uncanny ability of shit smell to transfer through 8-10 layers of quality toilet tissue to the wiper's hand,as if by osmosis. One tell-tale clue that you have acquired skinkmosis if if the wiping hand feels damp.
After pooping and wiping,I always do a stinkmosis sniff test to see if I need regular soap or germicidal gel or both.
