Tattoos and piercings

What comes to mind when you see someone with visible tattoos and/or piercings? Do any stereotypes jump out at you or are you able to see past the outer appearance? Does it matter if the person is male or female, black or white, young or old, thin or fat, etc.? As a person who is an advocate of decorating your body anyway you see fit, as long as if you choose something that will most likely offend some one or some group you're ready to face the consequences, I still find myself jumping to conclusions right off the bat at times. But the more my body becomes a piece of artwork, the easier it is to not make assumptions about others. If you have body modifications, have you ever had problems with others?
