Hell on Wrist

By marking "hell" on the left wrist, is this guy telling everyone that masturbating with his own left hand is like "hell"? Perhaps he is a "righty", and he has the tattoo of "heaven" on it.

Also he did not even get "hell" correct. The left partial in 獄 is missing a stroke.

地獄 = hell
