The yellow urine stains and residue often found and associated with public toilets.
The downside to living with guys is that they eventually get a case of peeboner&, the end result is that your gonna have to clean all the pissbutter off of the toilet.

2.
Urine that accumulates on the back of the toilet or one the bathroom floor over time to form a gravy-like paste known as piss butter.
I saw a guy on the internet that once scooped piss butter off the back of a toilet, spread it on a cracker, and ate it.
