I don't like tramp stamps anyway, but looking at the "art" by itself, there's just way too much going on to tell what it's supposed to be. Besides that, the middle circular thing isn't even close to being centered between the shitty tribal accents.
Tramp stamp? Skank plate? either way this is not very original, and very, very ugly. Too bad you cant take it back. Use a pot scourer and try scrub it out. A scar would be prettier than that.
