Diff: bait

 The part of a meme-complex that promises to benefit the host (usually in return for replicating the complex). The bait usually justifies, but does not explicitly urge, the replication of a meme-complex. (Donald Going, quoted by Hofstadter.) Also called the reward co-meme. (In many religions, "Salvation" is the bait, or promised reward; "Spread the Word" is the hook. Other common bait co-memes are "Eternal Bliss", "Security", "Prosperity", "Freedom".)
