The word means "to watch a large number of television programs (especially all the shows from one series) in succession." The word has become more relevant lately because it reflects the new way that many people view TV shows, due to video websites such as YouTube and streaming services such as Netflix. Commentators said that the word is used often because it is now common for viewers to binge-watch a whole season of programs in one sitting, which, in the past, would have taken months.
