This is no joke. Piercings too. Scientific studies have been done which confirm this. Physicians know a tattoo or nipple ring is correlated with up to a 10-fold increased risk of having AIDS-- usually not because of the tattoo or piercing directly, but because people who get tattoos and piercings tend to be promiscuous, drug-taking trash.
There are exceptions, maybe even here on FR, but in general a woman with a tattoo is a filthy slut that I wouldn't touch with the tip of my umbrella, much less take to bed.
We started discussing this with my daughter at about age 9. We told her she'd be kicked out of the house and we wouldn't pay for college if she got a tattoo or a piercing anywhere but her ears-- sure hope we never have to decide whether to follow through on our threat.
