whiskey plank
n.— «The whiskey plank, as it is called because sailors traditionally have a drink or ten after they finish planking a ship’s hull, was cut to fit by Teddy Huff, who has been working at the shipyard about five months.…When he put the final bolt in place, a cheer went up across the shipyard.» —“One last plank and a shot of whiskey make it real” by Brian Hicks Post and Courier (Charleston, South Carolina) July 22, 2006.
