I agree with doogie and ProfX. I have a couple, and neither of them are visable unless I want them to be. But whether or not people would like them is not the reason I got them. In fact it was kind of the opposite.
Don't get me wrong - they both mean way more to me than just being cool ink. And I could care less if anyone understands the meaning or not. But One of the reasons I got them was to kind of throw the bird at what people consider normal. I don't want to be put into that box, and if I can make a statement about it while at the same time pissing some folks off - well so much the better.
