Answer:
An activity or fashion that is taken up with great passion for a short time is called a fad. Fads can include a wide range of activities, products, or cultural phenomena that become popular for a brief period before losing popularity or becoming outdated. Examples of fads might include a popular dance craze, a particular style of clothing, or a viral internet challenge. Fads are often driven by social influence and can spread quickly through social networks or media, but they tend to be short-lived and are often replaced by new fads or trends.
