I live in Washington near Seattle, but I'll probably get this done in Portland, away from my parents >.> I'm gonna be moving there during the summer.
I'm 18,and part of it IS rebelling against my parents, but the tattoo itself I've always sort of wanted but never got because my parents don't like tattoos. That's all I'd be rebelling against.
Anyway, I know you all suggest getting a big jaguar itself, but if I'm allowed to be a little personal, I have this...belief about myself where I identify as a jaguar (non-physically, and in my case it's just psychological though for other people like me it can be spiritual), and since I can't actually become a jaguar, I want to have the pattern of one going down my back. Plus I don't think it'd be a particularly difficult tattoo to hide anyway. But yeah, like I said, it means a lot to me and helps me feel more...well, like a jaguar since I'll never be able to actually be one in any shape or form.
Edit: I have a character who has these tattoos, and I did this terrible drawing of her so I could show off her tattoos.

Edit again: I read the lower part of your message CultExciter, and while I agree with you on the getting big tattoo things, the thing is, this is the only tattoo I want to get. I'm pansy enough as it is, and I'm gonna stomach my way through it so I have something that I feel better represents myself, but I don't have any urge to get any other tattoos elsewhere, that's all.
