I plan on being tattooed there some day. I'd get some beautiful and intricate design or portrait. Think mural-style. I haven't totally planned it out yet, but it would cover my entire lower back, most likely. Or something smaller, but still fairly large and detailed, to one side on the back of the hip area. I'm not into like, some meaningless tribal butterfly crap right above my crack, haha.
I want either a heart with vines on my lower back or 3 stars on my hip. I think the stars would look cute when I pierce my belly button since I'll have a star chain thing. Tramp stamps are hot. Untill I get old.
