/mēm/
[coined on analogy with 'gene' by Richard Dawkins]
n. An idea considered as a replicator, esp. with the connotation that memes parasitize people into propagating them much as viruses do. Used esp. in the phrase 'meme complex' denoting a group of mutually supporting memes that form an organized belief system, such as a religion.
This lexicon is an (epidemiological) vector of the 'hacker subculture' meme complex; each entry might be considered a meme. However, 'meme' is often misused to mean 'meme complex'. Use of the term connotes acceptance of the idea that in humans (and presumably other tooland language-using sophonts) cultural evolution by selection of adaptive ideas has superseded biological evolution by selection of hereditary traits. Hackers find this idea congenial for tolerably obvious reasons.
