I was reading wikipedia, and it said in the US many people use the "5/4" definition.
But that really doesn't sound like binge drinking to me.
I always associated binge drinking with consuming an excessive amount of alcohol pretty much constantly for the duration of an evening (like constantly drinking for 6 hours).
According to the 5/4 definition, a binge drinker is a man who consumes five or more alcoholic drinks on an occasion of unspecified duration and is a woman who consumes four or more drinks on an occasion of unspecified length.
