I want to get a Sailor Moon tattoo just for memory purposes. And I want a ying/yang tattoo in between my shoulder blades (not very original, I know). And I want other Japanese tattoos. I'd have to think more about it though.
What tattoo do you have?
And no, getting your eyebrow pierced doesn't hurt at all. I've had mine done 5 times (I kept taking it out and then wanting it back. haha) and it didn't hurt any of those times. It just feels like a really quick pinch. That's it.
And no, I never think they have too many tattoos. The ones that do have tattoos/piercings look amazing with them. I'm getting tired of seeing lip piercings on JRockers though, I'll admit that.
