僕の彼女が怒った理由

My friend Paul from Taipei found this video on youtube and sent it to me. There is very little Japanese in it, but it still requires a bit of a translation. Let's just hope my translation is reliable, since some of it is far more colloquial than to what I'm used.

Introduction: The reason my girlfriend got mad at me.

Woman: What the hell are you doing?!?

Man: Why are you so mad?
Woman: Because of YOU!
