Tramp Stamp Tattoo?

So I'm 17 and I wanted a Tattoo for a long time, and I wanted it on my lower back because there people won't be able to see it unless im naked so I thought that was perfect place for it and then I started telling people and everyone is telling me to change it, and I'm just wondering if people really think people who have them there are tramps or whatever? I want either a four leaf clover or a pink and black shooting star. What message would this send to people? SHould I change it?
