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.
The Moomins are a bunch of tax dodging, work shy, hippo-like troll creatures from Finland. The word moomin is used to highlight or berate such people who, like the Moomins, consistantly avoid contributing to the welfare state!
"Look at that moomin getting his Giro!"
"I'm not giving you any 'bus-fare' you bloody moomin!"
