The Smurfs are a fictional group of small sky blue-colored creatures who live in Smurf Village somewhere in the woods. The Belgian cartoonist Pierre Culliford, sometimes referred to as Peyo, introduced Smurfs to the world in a series of comic strips, making their first appearance in the Belgian comics magazine Le Journal de Spirou on October 23, 1958. The English-speaking world perhaps knows them best through the 1980s animated television series from Hanna-Barbera Productions, The Smurfs as well as subsequent feature films.
A characteristic of the Smurf language is the frequent use of the word "smurf" and its derivatives in a variety of meanings. The Smurfs replace enough nouns and verbs in everyday speech with "smurf" as to make their conversations barely understandable: "We're going smurfing on the River Smurf today."
In "Emission Impossible", Stewie Griffin watches an episode of The Smurfs which spoofs the way the characters use the word smurf as a euphemism for an endless number of words, including sexual and swear terms. They are colored purple here as Seth MacFarlane did not have permission to use true depictions.
In "Halloween on Spooner Street", a female teenager is seen dressed up as Smurfette.
