wrinkling
n.— Note: “Wrinkle,” spelled with an R, is a regional name for the periwinkle. «Jobs like “wrinkling”—the local term for heading out into the intertidal zone at low tide and gathering periwinkles for sale to a local shellfish wholesaler. In a corner of Maine where incomes are rock-bottom and jobs are few and far between, Keene said, a few baskets of periwinkles can mean food on the table or gas in the pickup.» —“Harvest disturbs bay residents” by Bill Nemitz Portland Press Herald (Maine) Apr. 5, 2009.
