I'm angry. I'm very angry, Ralph. You know, you can ball my wife if she wants you to. You can lounge around here on her sofa, in her ex-husband's dead-tech, post-modernistic bullsh-t house if you want to. But you do not get to drive my f-ing automobile!
(Paraphrased from the movie "Heat" with Robert Di Niro)
I think it's more outrageous what he's most likely doing to the guy's wife.
