Faddisms are trends or fads that come and go relatively quickly, often without any lasting impact or significance. Common synonyms for faddisms include buzzwords, crazes, fashions, fashions, manias, trends, vogues, gimmicks, and passing fancies. These terms are all used to describe transient phenomena that have limited longevity or staying power. While faddisms can be entertaining or amusing in the moment, they seldom have any real substance or meaning. As such, they are often seen as superficial or trivial by those who value deeper or more enduring trends and movements.
