Meme (pron. meem): A contagious information pattern that
replicates by parasitically infecting human minds and altering their
behavior, causing them to propagate the pattern. (Term coined by Dawkins,
by analogy with "gene".) Individual slogans, catch-phrases, melodies,
icons, inventions, and fashions are typical memes. An idea or information
pattern is not a meme until it causes someone to replicate it, to repeat it
