"In a press release today, Netflix announced that “8.4 million members” have begun binge racing. This watching strategy, which is to complete a series during the 24-hour period following its release, has grown “more than 20 times over” since “binging” itself became common vocabulary. 200,000 racers in 2013 became more than 5 million as of last month. The behavior is changing, but it’s also changing what TV means to its audience."
There. You could've just answered the definition of binge racing. It's called asking a damn question for something you legitimately don't know about. It's called learning from the world.
