I am a tattoo owner...they are a part of me not just some fashion fad but I agree with most ofthe posters here...there are some styles that I like and some that I don't but it is not up to me to say what some other person should or should not have for a tattoo.
I do try to talk to young people who ask me about my tattoos and I stress the them that it is a lifelong statement and they should really think about what they may want before rushing into a shop and getting a "Bart Simpson' mooning or flipping the bird. Even then...if that is what they want and it has meaning to the...more power to them, its their skin.
For most people tattoos have a very person meaning but the lastthing I thing or worry about when I get a new tattoo is "Oh my God...what will other people think". In fact in the case of my "Kruppel" tattoo, the whole point is to make people ask what it means and hopefully feel a little uncomfortable so that they think about the issue.
ONE WORK OF WARNING TO WOMEN.....If you are a young woman you may want to think carefully about tattoos over your kidney or lower back area. My wife works in the surgical unit of a large regional hospital and many Anesthesiologists (sp) will not perform an (epidural ? / Spinal) whichever...many won't use that location for anesthesia during surgery if there is a tattoo there...like for childbirth.
