What term describes consuming five drinks in a row at least once in the previous two weeks?

The term that describes consuming five drinks in a row at least once in the previous two weeks is binge drinking. Binge drinking is defined specifically by the quantity of alcohol consumed within a short period, often used in public health discussions to highlight risky drinking behavior that can lead to negative health outcomes. It is typically associated with episodes of heavy intoxication, and research suggests that this pattern of drinking increases the likelihood of accidents, injuries, and long-term health issues.

Heavy drinking, while related, generally refers to a more sustained pattern of consuming larger amounts of alcohol over an extended period rather than focusing on a singular episode. Social drinking usually implies moderate consumption in social settings without specific quantities, and frequent drinking denotes regular alcohol consumption but does not specify the volume or rhythm of drinking episodes. Thus, binge drinking is the correct term for the scenario described in the question.
