A combination of a milf with the intense anger fluctuations of Lou Ferrigno that you might expect from a post-menopause milf that you are currently banging. Basically she goes Hulk on your ass.

Doug: "Great". "Until I mentioned i would totally do her hot 19 year old daughter, then she turned all milferrigno on me."
