>ChatGPT, please define "fad".

>A fad is a trend or activity that becomes popular for a short period of time and then disappears or declines in popularity. Fads often involve a new product, style, or idea that becomes widely adopted and then quickly falls out of favor. Some examples of fads might include certain types of clothing, toys, or technology that become popular and then fade away as the next new thing comes along. Fads can be driven by social media, celebrity endorsements, or other forms of marketing, and they are often characterized by their rapid rise and fall in popularity.
