Hmmm… this one seems a bit odd to explain.
Is there a way to say “You X!” instead of “You are X!”? For example: “You idiot!” as opposed “You are an idiot!” or “You tight-fisted bastard!” instead of “You are a tight-fisted bastard!” (is that PG-13? I don’t really know :P).
Oh, I just thought of another question in the same vein: how would you say “You are one X Y! :D”. Like… “You are one sly dog! hehe” or “You are one special lady! ;)”.
