Nunchi (Korean)

Why is it some people just seem to have no idea what's going on in a social situation? They tell six jokes in a row without noticing no one is laughing, they smoke in a house that has clearly never been smoked in, they managed to always bring up the one subject you're sensitive about ("Hey, you know what's funny? The Holocaust!")

The Koreans would say they lack nunchi, the innate ability that lets you sense what would be the wrong thing to say in a situation (and presumably the ability to then not say it).

The boss character from The Office (both versions) is simply a guy who completely lacks nunchi. It goes beyond tact, or simple manners. It's the ability to read your audience and instinctively know, as soon as you see them, "here are people who will not enjoy my dildo anecdote."
