the term "purge binge" is not a standard or widely recognized phrase. It is possible that new terms or phrases have emerged since then, but without further context, it is challenging to provide a definitive answer.
In general terms, "purge" and "binge" are two distinct behaviors often associated with eating disorders like bulimia nervosa. A "binge" refers to a period of uncontrollable and excessive consumption of food, often done in a short amount of time. On the other hand, "purge" refers to the compensatory behavior that follows a binge, where the individual tries to rid their body of the excess calories consumed. This may involve self-induced vomiting, excessive exercise, or the use of laxatives.
However, without more information about the specific context in which you heard or encountered the term "purge binge," it is difficult to provide a more accurate explanation. If it refers to something else entirely, I would need additional details to assist you better.
