I heard the following on 'The Office' in episode Downsize (#1.1):
David Brent: I'm going to have to let you go first.
Dawn: What? Why?
David Brent: Why? Stealing. Thieving.
Dawn: Thieving? What am I meant to have stolen?
David Brent: Post-It notes.
What does the 'what am I meant' part mean here? Is it a common expression used in BrE or AmE? Cant we simply say: What have I stolen? What might have I stolen?
