Yankee dime
n.— «“Yankee dime” is a slang term used in some sections of the United States, particularly in the South, to denote a kiss, just as “Dutch quarter” is used to mean a hug. In some sections “Quaker nickel” is employed in the same sense as “Yankee Dime.”» —“Colloquial” Indiana Weekly Messenger (Pa.) June 7, 1928. (source: Double-Tongued Dictionary)
