What is "sniglet"

n. An often humorous word coined to define something for which no previous word existed; a protologism.

Sniglets a type of neologism, were popularized by comedian/actor Rich Hall during his tenure on the 1980s HBO comedy series Not Necessarily the News, each monthly episode of which featured a regular segment on "sniglets," which Hall described as "any word that doesn't appear in the dictionary, but should." Possibly originating in a game devised by author Douglas Adams and British comedy producer John Lloyd, sniglets were generated and published in significant number, along with submissions by fans, in several books, beginning with Hall's Sniglets, Sniglets for Kids, and More Sniglets in the mid-1980s.
