parasytic
Parasytic refers to a phenomenon or entity that exhibits parasitic behavior. Parasitism is a biological relationship where one organism, the parasite, lives on or in another organism, the host, and harms it. The parasite benefits by deriving nutrients or other resources from the host, while the host is negatively impacted. This can range from microscopic organisms like bacteria and viruses to larger animals like ticks and fleas. In a broader, non-biological context, "parasytic" can describe anything that drains or exploits another entity for its own gain, such as a financially exploitative business practice or a person who relies excessively on others without contributing. The key characteristic is an unequal relationship where one party benefits at the expense of another.
