meme
/meem/ [coined by 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 tool-
and 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adaptive ideas has superseded biological evolution by selection of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.
