In my opinion, it was a very simple reference to the childhood wound caused to Joker by his father...His father deformed his face using a simple kitchen knife...of course, that does not kill him but made him...a stranger....
I think he may have been alluding to his scars. He takes his mask off right when he says "..stranger." and then smiles and gets up. Maybe he was saying that though he wasn't killed when he was deformed, it did make him "stranger" in a sense.
