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.

Similar to "Don't rain on my parade". No one wants piss in their butter (obviously) so it insinuates someone ruining a situation.
After cooking for 3 hours, my friend complained about the napkins so I said "Don't piss on my butter!"
