jargon

jargon, pejorative term applied to speech or writing that is considered meaningless, unintelligible, or ugly. In one sense the term is applied to the special language of a profession, which may be unnecessarily complicated, e.g., “medical jargon.” Jargon can also mean clumsy language that is hard to understand, synonymous with gibberish or gobbledygook, or a mixture of languages that serves different people (see lingua franca).
