That's why he had it tattooed on his arm and used it repeatedly as a sort-of assumed identity. Because it meant absolutely nothing to him.
It's possible, I guess. It's also the least likely scenario I've heard since the speculation started.
Look at the pictures he sent to NBC......there's NOTHING on either arm.
May point is that it looks like people are going way overboard trying to find a meaning to something that may have only meant something to him and has no real reference to something in reality.
