Negative Planetariums

The term for when a woman's breasts are so covered with moles that they resemble two inside-out planetariums with inverted color schemes, the moles of course being the stars and planets.

Eric: So I picked up this girl at the campus bar and brought her back to my dorm, but as soon as i had her shirt off I realized she had moles everywhere. Her tits were like a couple of negative planetariums.

Steve: Did you find the big dipper?

Eric: Well she sure didn't, if you know what I mean.
