I just learned the best word: fremdschämen. It's German, obviously, and it means vicarious embarrassment, or as the New York Times put it, "a feeling of cringing embarrassment for the actions of others."
Dude, you guys, I have that all the time. That's why I hate movies like "Meet the Parents" and the sequel that I refused to even see. Even sitcoms make me cringe. I have no desire to watch people embarrass themselves (or injure...I'm looking at you, AFV) because it makes embarrassed for them.
So, yeah, let's work that into everyday conversation. Fremdschämen. You're welcome.
