vengeance pee
When your pet dog or cat deliberately takes a piss on a rug, furniture, or article of clothing in an act of revenge or retaliation for something you have done to piss them off, or deny them.
What a bastard, I walked the dog 2 hours ago and there is a piss spot right under my computer desk, this is definitely a vengeance pee for denying him those ribs we were cooking.
