Binge drinking is the modern definition of drinking alcoholic beverages with the primary intention of becoming intoxicated by heavy consumption of alcohol over a short period of time. Or alternatively, a consistent amount of alcohol over a long period of time. It is a kind of purposeful drinking style that is popular in several countries worldwide, and overlaps somewhat with social drinking since it is often done in groups. However, it is also done alone as a method of self medication. The exact degree of intoxication, however, varies between and within various cultures that engage in this practice. Formerly, most countries defined the term as a multi-day heavy drinking session during which the drinker neglects usual responsibilities and otherwise behaves recklessly. In Russia, many people often still define it this way.
