This is a leg tattoo of Hulk flipping the bird. Plus he has his name tattooed on his knuckles because sometimes he's so busy raging he forgets it. Hey, when I'm partying hard I do the same thing. "Here's your beer, what was the name on your tab?" JAGERMEISTER.
Thanks to Glen, whose leg that might actually be. It looks like the face and hand were done by two totally different people.
