You 'da man!
or
You are that man.

In my ESL classes we talk a lot about the fact that HOW you say something is as important as the words you choose. I don't think Nathan was high-fiving David in the readings for Sunday.

What does that mean? You are the man? Besides being the man in the parable, I mean. What kind of man is David? What kind of man was the man in the parable? Uh-oh... what kind of people are we?

More on this as things develop.
