New tattoo dilemma, please help?

I never used to like tattoos when I was younger, but when I met my husband (who has a gazillion) I started to like them. I have a tattoo on my right hip of two roses and my husband's name and I swore I wouldn't get another. As you can guess, I've started to contemplate getting another one. I don't really like it when you can see a girl's tattoo and I kind of want one that has something to do with my rebellious streak, but I can't think of anything! Any suggestions?
