"The potlatch is a festival or ceremony practiced among Indigenous peoples of the Pacific Northwest Coast. At these gatherings a family or hereditary leader hosts guests in their family's house and hold a feast for their guests. The main purpose of the potlatch is the re-distribution and reciprocity of wealth." (http://en.wikipedia.org/wiki/Potlatch)
