Don't say "That's F---ed up!" when referring to the way someone does business, talks, walks, dances, eats, combs his/her hair, dresses, listens, sleeps, or describes his childhood memories. In fact there are rarely any occasion where such a reaction is acceptable. If you do find yourself about to say such a thing just remember, you're just as f---ed up as they are only in a different way.
This is just another of my many etiquette tips.
