Minor tattooing = good
Arm sleeves = weirdo
Minor tattoing=boring, i.e. tramp stamp is a dime a dozen
Now, too many piercings can be weird. 3+ per ear is a bit much. It also depends on the girl. If she has the personality to pull off a nose ring or double sleeve tattoos, awesome.
Also, I could go for a girl like the one in the picture above.
