Moomins 

A woman's breasts. Especially when large and shapely.

The girl sat at the desk opposite from me keeps shaking her moomins at me.

Look at the moomins on her!

moomin 

The Moomins are the central characters in a series of books by Finnish writer Tove Jansson, originally published in Swedish. They are a family of Scandinavian trolls who are white, round and furry in appearance, with large snouts that make them resemble hippopotamuses. The carefree and adventurous family live in their house in Moominvalley, though in the past their residences have included a lighthouse and a theatre.

Moomintroll - the main character of most of the books, a spirited teenager with a keen sense of adventure and fun, and a generous spirit.
