Why don't my shit and urine stink while they're inside me? - Lemmy.World

If you put fresh shit in a closed box, it will still stink up the whole room, but the shit in my ass will barely stink even if my ass is on your face, although there is a hole there. Why

They still stink if you let some air through by farting. Boxes are rarely airtight, whereas assholes usually are.

Source: I have a plastic box that I often put some acetone in. And sometimes I fart. The two are not related.

*Notes* Posession of box of acetone… does NOT… make farts happen.
Possibly because I also have a small fan running inside the box
Damn all these variables!
