Arretez ! Sa question était pas bete !
Voici une réponse en anglais :
" What is a meme?"
Glenn Grant: 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 to someone else. All transmitted knowledge is memetic.
Si qqes uns d´entre vous s´y connaissent en anglais...
