-a verb, an act
The act of your wife or girlfriend putting her cold ass butt on you while you are sleeping or on the couch. It's common in women of all ages. They never stop doing it, and they don't much care if you get frostbite from it. It matters very little if she is in fact smoking hot. Her butt is always cold. She may also do it if she wants a butt rub.
Did you sleep well last night babe?

Well, I did almost freeze to death after you decided to butt prop me
