"The Norwegian word Dugnad (pronounced doog nahd) describes a special way of doing voluntary, communal work. When someone needs a hand, either to clean out the garage, prepare the garden for winter or to build an extension to their cottage, they call together neighbors, friends and family for a working party. Serving soda and snacks during work and perhaps a beer when all is done, the Dugnad is a social event as much as it has been an important tool for building Scandinavia and its social relations."

- from http://www.projekt0047.com, a site promoting two socially / community based firms that do projects solely to benefit communities. although, i suspect from the amount of norwegians, swedish and danish that i have met, a 'dugnad' will involve WAY more than "one" beer, and wont be restrained to "when all is done." ha ha ha
