Barbie,
I think it's the red rouge in the lipstick. Back in your Dad's day, we used to give girls our class ring when we were "goin' steady." They were 18k gold and silver back then. Don't know what they are these days. They'd slick em up with lipstick and polish them, then wrap the bottom with a wad of mohair yarn until it fit their finger. I think it's how they marked their territory.
