An expression that implies one is being overly subtle while doing something common - such as talking. Similar to the way one would urinate on the bowl of a toilet or urinal to avoid creating an audible noise.
I want to call my boss an asshole, but I can't. I'll just piss on the porcelain about it for self-satisfaction.

Get the piss on the porcelain mug.The act of urinating so forcefully that anyone in earshot is convinced you have a hatred of toilets/urinals.
I held it for so long that when I finally went, the guy next to me said "you were pissing like you hate porcelain."
