Just my opinion here...
I don't understand why girls write on themselves. It's not something I find appealing even a little bit. I don't care if it's boyfriend's name, daddy's name, great aunt's name or a picture of the god you worship - I feel the same way about all of them. I had a friend that would get tattoos to cover her stretch marks. I always thought it was so bizzare lol. She had them ALL over. I have seen tats that I thought were cool for the wearer but not for me the way I look at it is - I have a gorgeous body as it is. Why would I paint over it? What happens when you paint over a masterpiece?
As for tattoos I find super unappealing, I'd have to say tramp stamps. I find the unoriginal ones very tacky. However, I know a girl that has has sleeves and it's so fucking hot on her (pic below). I have seen other girls with it and they're not nice looking at all.
See?
