I've never been a huge fan of tattoos, but, um, imagine I got one like THIS on the back the back of my neck, really small, so you'd only really see it if my hair was tied up.
I'm not a fan of heavy black tattoos and I've never really seen anyone with a brown one like this. At first glance it kind of just looks like a birth mark, it's not all black and inky and up in your face, it's subtle, I like it, a LOT.
