<human>:  In the world of Harry Potter, would a snake and skull tattoo be good luck?
<bot>: No, a snake and skull tattoo would not be good luck in the world of Harry Potter. A snake is a limbless, scaly, elongate reptile. In Harry Potter, a tattoo of a snake and a skull is a symbol of being a "Death Eater." Death Eaters are people who follow the word of the dark lord Voldemort.
