What that woman does with her jacket after she poops is disgusting, and whoever finds it is even worse

A woman in Japan is filmed defecating in an alley. Afterwards, she uses her own jacket to wipe herself, then leaves it behind. A man finds it a little later. He notices something on the fabric, touches it with his fingers, then decides to taste it. We don't know why he does this. He doesn't seem bothered by the smell or the appearance. The video shows the scene uncut, which makes everything even more incomprehensible.
