A person who knows how to get drunk as inexpensively and efficiently as possible, with the least possible adverse side effects to their health. Such behavior may include, but not limited to: pre-drinking before clubbing, therefore having to buy less alcohol. buying drinks which have more alcohol for less money. Scoping out the bar in a club and moving in when there is little or no line. And drinking to the point of enjoyable intoxication without making oneself sick.
