1. They're not afraid to stand out.
This one is a no brainer. Even though tattoos are not taboo like they were in times past, inked people still stand out more than the in-inked variety. And you know what? It doesn't bother them one bit. In fact, people with tattoos like to stand out. They like to show their uniqueness. If they didn't, they probably wouldn't have gone through the time, pain, (and money) to get the ink in the first place. Now this doesn't only apply to extrovert, outgoing people.
