dildo

Definitions

Slang

  • noun an artificial penis. The word is approximately 200 years old and probably originates in diletto, Italian for (a) delight or darling. Alternatively the term may simply be an invention.
  • noun a fool, an offensively stupid person. This sense of the word, popular among teenagers since the mid-1970s, may be an embellishment of dill as much as a derivative of dildo 1.
