A girl whose unusually short stature and remarkably plump physique give her a rather round appearance which resembles that of a small planet. Like Pluto. When a group of short and plump girls is spotted entering a social event (since they prefer to travel in packs) they can be referred to as a solar system rolling through.
Dude! I can't believe you made out with that small planet!

I don't like skinny chicks, I prefer small planets ;)

"Where are all the small planets at though!?"
-guy who likes short fat chicks

Oh man! That small planet might go into orbit any second!
