gedunk
n.— «You possess one comic feature that is changing the habits of the nation. I refer to Harold Teen and his Gedunk sundae. I have two children, a boy and a girl, now of high school age, and I have spent many a painstaking hour teaching them correct table manners. Their conduct was above reproach until the notorious Gedunk sundae made its appearance.» —“Gedunk Sundaes” by E.A. Edmonds Chicago Daily Tribune Mar. 10, 1926. (source: Double-Tongued Dictionary)
