Buttload - Tumblr Posts

The term "butt" refers to a specified volume, measured in either imperial or US customary units, typically used in reference to alcoholic beverages like wine, ale, or cider. A butt is approximately equivalent to 108 imperial gallons (130 US gallons; 491 liters) for ale or 126 imperial gallons (151 US gallons; 573 liters) for wine, though it's worth noting that the Oxford English Dictionary mentions that these standards were not consistently followed with precision.

Therefore, a “buttload” is an actual unit of measurement.
