A nano-mesite or nano-micrite replicator (usually a sophisticated meso- or micro-scale cytobot or cytobiobot with extensive bionano firmware) that inculcates in the target a predisposition towards a particular meme, usually by subtle alteration of brain chemistry in conjunction with subliminal messages. Membots are expensive, unreliable, easily detected, and almost universally outlawed throughout much of civilized galaxy. This does not prevent their widespread use, especially among ruthless corporations and cults operating out of feral regions or free zones.
Facetiously, a person whose entire life has become subordinated to the propagation of a meme, automatically and at any opportunity. (Such as many religious and cultic types.) Due to internal competition, the most vocal and extreme membots tend to rise to top of their sociotype's hierarchy. A self-destructive membot is a memeoid.
Meme-complex, Memeplex - Text by Glenn Grant A set of mutually-assisting memes which have co-evolved a symbiotic relationship. Religious and political dogmas, social movements, artistic styles, traditions and customs, chain letters, paradigms, languages, etc. are meme-complexes. Types of co-memes commonly found in a scheme are called the: bait; hook; threat; and vaccine. A successful scheme commonly has certain attributes: wide scope (a paradigm that explains much); opportunity for the carriers to participate and contribute; conviction of its self-evident truth (carries Authority); offers order and a sense of place, helping to stave off the dread of meaninglessness.
Memetic Infector - Text by M. Alan Kazlev A sapient being used to infect societies or communities with a partiucular memeset. Memetic infectors resemble ordinary sophonts, but may differ psychologically, often having fanatical or one-sided enthusiasm for the meme-plex they are carrying. Infectors may be replicators (viruses) or non-replicators (memengers).
Memeticity - Text by M. Alan Kazlev A meme-complex, a coherent aggregation of component memes that itself constitutes a larger meme. Philosophies, ideologies, worldviews, and religions are all memeticities.
