Lol, but on seccond thought, no...
Imagine urself a man with a serious job, and u got a tatto on ur arm...
For a teen its cool, but im sure i would regret it when i grow up...
I know U could have it erased, but, well u know what I mean :S
I guess they're ok but I have no reason to hurt my skin with one. Why would I take one? They very seldom even make you more beautiful, and if it's a rebel thing, as an adult I really don't have anyone to rebel against, not anyone/-thing that would note a tattoo anyways.
