Twonkie

n. The software equivalent of a Twinkie (a variety of sugar-loaded junk food, or (in gay slang) the male equivalent of 'chick'); a useless 'feature' added to look sexy and placate a marketroid (compare Saturday Night Special). This may also be related to "The Twonky", title menace of a classic SF short story by Lewis Padgett (Henry Kuttner and C. L. Moore), first published in the September 1942 'Astounding Science Fiction' and subsequently much anthologized.
