Kosei - what is it?

Something found in the inner rectum, with a disgusting smell that is surprisingly satisfying. The human manifestation of such a thing, would most definitely be a pervert. A pervert who likes to touch the Koseis of other men.

*sneaks up behind a guy taking a dump* "Hey man, can I feel your Kosei"
"Ew, get away from me perv!"
