Cornball and corny are two terms used in American English to refer to something old-fashioned, sentimental, treacly. A corn ball, two words, is an American snack made from popcorn mixed with a hard syrup and fashioned into a ball. Corny may also may be used to mean something that is full of corn, the vegetable. The terms cornball and corny arose in America in the early 1930s to mean something old-fashioned, something sentimental, something that appeals to plain country folk. At that time, country people were referred to as corn-fed, therefore something that appeals to plain-thinking people would be corny or cornball. Related words are cornily and corniness.
