Looks like the backside of the old woman in the tube where Jack Nicolson thought he was makin out with some babe and she turned into that ! (The Shining)
First pic looks like it is on the left lateral abdominal area, plus there is a dolphin tattoo? the last ones show no dolphin, but ewww....still wonder, my guess is it's a woman, but any idea?
I don't think it's a tattoo. It's where the surgeons made a mark to do the surgery.
