To most people, binge drinking brings to mind a self-destructive and unrestrained drinking bout lasting for at least a couple of days during which time the heavily intoxicated drinker "drops out" by not working, ignoring responsibilities, squandering money, and engaging in other harmful behaviors such as fighting or risky sex. This view is consistent with that portrayed in dictionary definitions, in literature, in art, and in plays or films such as the classic Come Back Little Sheeba and Lost Weekend or the recent Leaving Las Vegas.

It is also consistent with the usage of physicians and other clinicians. As the editor of the Journal of Studies on Alcohol emphasizes, binge describes an extended period of time (typically at least two days) during which time a person repeatedly becomes intoxicated and gives up his or her usual activities and obligations in order to become intoxicated. It is the combination of prolonged use and the giving up of usual activities that forms the core of the clinical definition of binge.

Other researchers have explained that it is counter-productive to brand as pathological the consumption of only five drinks over the course of an evening of eating and socializing. It is clearly inappropriate to equate it with a binge.

A recent Swedish study, for example, defines a binge as the consumption of half a bottle of spirits or two bottles of wine on the same occasion. Similarly, a study in Italy found that consuming an average of eight drinks a day was considered normal drinking -- clearly not bingeing. In the United kingdom, bingeing is commonly defined as consuming 11 or more drinks on an occasion. But in the United States, some researchers have defined bingeing as consuming five or more drinks on an occasion (an "occasion" can refer to an entire day). And now some have even expanded the definition to include consuming four or more drinks on an occasion by a woman.
