&gt;There is currently no worldwide consensus on how many drinks constitute a "binge", but in the United States, the term has been described in academic research to mean consuming five or more standard drinks (male), or four or more drinks (female),\[12\] over a two-hour period.\[13\] In 2015, the US Centers for Disease Control and Prevention, citing the National Institute on Alcohol Abuse and Alcoholism, defines binge drinking as "a pattern of drinking that brings a person's blood alcohol concentration (BAC) to 0.08 grams percent or above. This typically happens when men consume five or more drinks, and when women consume four or more drinks, in about two hours."\[14\] and estimated that about 16% of American adults met these criteria at least four times per month. One 2001 definition from the publication Psychology of Addictive Behavior states that five drinks for men and four drinks for women must be consumed on one occasion at least once in a two-week period for it to be classed as binge drinking.\[15\] This is colloquially known\[by whom?\] as the "5/4 definition", and depending on the source, the timeframe can vary.

From Wikipedia. Seems like anything taking you over the limit for driving was the original intent and some have started to use what was meant as an example as a new definition.

The limits used in Finland, called "moderate risk" and "high risk" are  14 and 23-24 drinks in a week (a glass of wine or a small beer is considered a drink)

Even in the US, there isn't a consensus on what binging is. I actually changed health providers two years ago because the labeled and we're treating me as a regular binge drinker. Because I had more than three drinks a week... I have one glass of wine a night.
