"russ celebration"

The russefeiring (English: "russ celebration") is a traditional celebration for Norwegian high school pupils in their final spring semester. Pupils that take part in the celebrations are known as russ. The russefeiring traditionally starts around 20 April (with some starting earlier/later depending on the regional county) and ends on 17 May, the Norwegian Constitution day. Participants wear coloured overalls (Usually red, blue, or black). Some form groups that name a bus, car or van.
