12-ounce curls
idiomThe activity of drinking beer.
Origin
disputed originFrom the size of common beer containers (bottles and cans) in the United States: 12 ounces + curls, a weightlifting exercise. The notion is of lifting a can of beer to one's lips repeatedly.
After a long week of manual labor, the crew sat on the porch and enjoyed some 12-ounce curls.
The weary workers gathered at the tavern to engage in a few 12-ounce curls before heading home for the weekend.
