A fad, trend, or craze is any form of collective behavior that develops within a culture, a generation, or social group in which a group of people enthusiastically follow an impulse for a short time period.
Fads are products or behaviors that achieve short-lived popularity but fade away. Fads are often seen as sudden, quick-spreading, and short-lived events. Fads include diets, clothing, hairstyles, toys, and more. Some fads in the last hundred years include toys such as yo-yos, and hula hoops, and fad dances such as the Macarena, floss and the twist.
