It's just a doodle inspired by a tattoo design of Ouroboros, (a dragon eating it's own tail). I had to look it up on Wikipedia, and found out that in the mythology of many cultures it represents a sort of phoenix, symbolizing rebirth, immortality, and duality. I like that by humanizing half of the dragon with a gut, legs, shoes, and even a cigarette, I'm polluting the original symbolism connected to it. To be human, we're sorta throwing out the potential rebirth, immortality, and duality. It's a strange serpent in the garden of eden.
