The term 'Silly Bandz or Webkinz, Once' can be summarized as a FAD. Fads are short-lived trends that become popular quickly and then fade away just as quickly. Silly Bandz and Webkinz were two popular fads in the early 2000s. Silly Bandz were colorful rubber bands shaped like animals, objects, and other designs, while Webkinz were stuffed animals with an online component. Both of these fads were popular for a few years before fading away.
