a Petrie
A Petri is when you and all your pets try to fit in one bed like you're all insane and also in love.
My dog, my cat, and my hamster tried to fit in my bed. It looked like a disaster zone.
Petri and his three dogs tried to sleep in one bed. It looked like a warzone.
My sister, her two cats, and her turtle tried to sleep in one bed. It was a disaster.
