The word has traditionally referred to things that have become unfashionable or outmoded. Later it came to refer to things that were socially unacceptable to the viewing audience perhaps because of the viewers social standards. Within certain geographic areas of vermont and new hampshire it has taken on a new meaning - basically referring to things that generally suck ass.
Common usage includes sayings such as "My ex is so dated."
