Water Nipple 

When a boob is slightly under water (most bathtub scenes) and you can see a slightly discolored spot in the water where a nipple is hiding underneath the surface. Kind of like a cave dwelling spider, you know it's there but you can't quite see it.

Chase-"Holy shit that is her water nipple!, man I love "Mirrors."
