Gaudy or gaudie (from the Latin, "gaudium", meaning "enjoyment" or "merry-making") is a term used to reflect student life in a number of the ancient universities in the United Kingdom. It is generally believed to relate to the traditional student song, De Brevitate Vitae (On the Shortness of Life), which is commonly known as the Gaudeamus by virtue of its first line.
