Mr. Cardboard's definitions
Pissing in the sink instead of the toilet. An act which saves water and is therefore good for the planet but enrages women purely because they can't do it due to their defective chromosomes, causing them to make ridiculous claims such as "it's disgusting" when we all know that urine is sterile as it leaves the body.
"You better not be doing a sinkpiss again!"
"I pay the water bill bitch so until you let me put a urinal in the bathroom I'm sinkpissing!"
