I call my belly bar just that. My belly bar. :)

Or alternatively, just 'belly piercing'. As in "Would you like to see my belly piercing?"

Also, just looking at thos Lisa pics you posted before... How long ago was that picture? (She looks young, but it could just be how she's dressed.) How hot would it be if she still has it? Like, I didn't think it would be possible for her to be hotter than she already is? But this would do it, I think.
