limpet

The biological sense refers to a specific type of marine gastropod known for its extreme tenacity. The word evokes an image of an unbreakable bond between the organism and the hard surface it inhabits, making it a vivid descriptor for physical adhesion.

When used to describe a person, the term carries a negative or slightly mocking connotation. It suggests a lack of independence or an overbearing emotional dependency. Unlike "loyalist" or "devotee," which are positive, "limpet" implies a suffocating or clingy nature that may be perceived as irritating by the person being clung to.
