Gask, gasque, a kind of Swedish student party which starts with a more or less formal dinner. The word is believed to originate from the card game vira, popular in the 19th century.
In some cities gask is generally used to refer to a party where the dress code requires tuxedo or formal jacket. Students at Stockholm University and the Royal Institute of Technology generally use the term gasque to refer to a gask where the dress code is a student overall.
In some cases Gasque might also be the name of an actual building, often a building belonging to the student union arranging the gasque, as in the case of Chalmers University of Technology in Gothenburg.
