you would increase the concentration of urine, but still nowhere near enough for it to create mustard gas when mixed with bleach. And you'd have an upset gut .n.
One time our sewer pipe got clogged with tree roots and we had to wait a couple of days to get it fixed. We left if we needed to go number 2 but would still pee in it. It started to smell so I decided to pour bleach in it. It started fizzing and gave off an awful smell. It started coming up the tub drain too. It stunk up the whole house. We had to seal off the bathroom for a few days. So that's how I accidentally tried to kill my whole family.
Men are weird.
He's still weird tho
