Corporate jargon

Corporate jargon (variously known as corporate speak, corporate lingo, business speak, business jargon, management speak, workplace jargon, corporatese, or commercialese) is the jargon often used in large corporations, bureaucracies, and similar workplaces. The language register of the term is generally being presented in a negative light or disapprovingly. It is often considered to be needlessly obscure or, alternatively, used to disguise an absence of information. Its use in corporations and other large organisations has been widely noted in media.

Marketing speak is a related label for wording styles used to promote a product or service.
