Google the meaning of backpfeifengesicht and see if it doesn't evoke Joe Lieberman!!
You looked it up? See what I mean? What is it about that face? Would it evoke the same feeling if you didn't know who the man wearing it was, and what the man wearing it was thinking, and what the man wearing it was doing as a result of what he was thinking?
Of course. Because the smirking arrogance oozing from that face is all the assurance you need that whatever the man is thinking and doing cannot be good for you, your children, your friends, your children's friends, or anyone else you care about. You can thank the Germans for putting a word to your feelings when you think again about what's behind that face.
