{Ed}: Myrna, can you run get me another roll of assiton assimilators please? This roll fell into the can, becoming toilet bowl paper!
{Myrna}: Ed, that's the third time this month that you've made toilet bowl paper! Won't you please fix the TP dispenser?!?
When you are taking a shit and your dick touches the cold porcelain at the front of the toilet, causing discomfort and in the case of public toilets, absolute disgust.
The brown water or piss or liquid shit that comes out of your ass, Brown in the toilet bowl like stout beer is brown in your glass hence the name toilet bowl stout.
