VirianLexicon:infectionstrategy
Any memetic strategy which encourages infection of a host. Jokes encourage infection by being humorous, tunes by evoking various emotions, slogans and catch-phrases by being terse and continuously repeated. Common infection strategies are "Villain vs. victim", "Fear of Death", and "Sense of Community". In a meme-complex, the bait co-meme is often central to the infection strategy. (GMG)
