a) An organization or entity whose sole purpose is promoting its own existence and splendor.

b) Any act whose primary consequence is the agrandizement of the actor

In both instances, the organization and/or act are inherently useless.
Armed Forces celebrating Memorial Day and Veterans' Day or the Catholic Church preaching from its own translation of the Bible are about as useful as a self-licking ice cream cone.
