n. 1 (context ecology English) Interaction between two organisms, in which one organism (the parasite) benefits and the other (the host) is harmed. 2 (context figuratively English) A similar interaction between people.
n. the relation between two different kinds of organisms in which one receives benefits from the other by causing damage to it (usually not fatal damage)
In biology/ ecology, parasitism is a non- mutual symbiotic relationship between species, where one species, the parasite, benefits at the expense of the other, the host. Traditionally parasite (in biological usage) referred primarily to organisms visible to the naked eye, or macroparasites (such as helminths). Parasites can be microparasites, which are typically smaller, such as protozoa, viruses, and bacteria. Examples of parasites include the plants mistletoe and cuscuta, and animals such as hookworms.
Unlike predators, parasites typically do not kill their host, are generally much smaller than their host, and will often live in or on their host for an extended period. Both are special cases of consumer-resource interactions. Parasites show a high degree of specialization, and reproduce at a faster rate than their hosts. Classic examples of parasitism include interactions between vertebrate hosts and tapeworms, flukes, the Plasmodium species, and fleas. Parasitism differs from the parasitoid relationship in that parasitoids generally kill their hosts.
Parasites reduce host biological fitness by general or specialized pathology, such as parasitic castration and impairment of secondary sex characteristics, to the modification of host behavior. Parasites increase their own fitness by exploiting hosts for resources necessary for their survival, e.g. food, water, heat, habitat, and transmission. Although parasitism applies unambiguously to many cases, it is part of a continuum of types of interactions between species, rather than an exclusive category. In many cases, it is difficult to demonstrate harm to the host. In others, there may be no apparent specialization on the part of the parasite, or the interaction between the organisms may remain short-lived.
Social parasitism is a pejorative that is leveled against a group or class which is considered to be detrimental to society. The term comes from the ancient Greek (parásitos), "one who lives at another's expense, person who eats at the table of another," used to label the social offender. (The English language borrowed the word/concept "parasite" as a social label in the 1530s; the later use of " parasite" as a biological metaphor developed from the early 17th century.)
For example, the Russian poet Joseph Brodsky was charged with social parasitism by the Soviet authorities in a trial in 1964, who found that his series of odd jobs and role as a poet were not a sufficient contribution to society.

After the Fall, after the Core lost control of the Hegemony via its dataspheres and far- casters, after the Core lost its greatest computing engine -- its direct parasitism on the billions of human brains as they transited the Void Which Binds via the so-called farcasters -- the TechnoCore had to find a new way to exploit humankind.
With the cruciforms, this parasitism on the human brain has been resumed.
