The term 'FADS' is an acronym for 'FADS, Autos, Drugs, and Sex, ' which were popular in the 1980s and 1990s. Pet Rocks and Beanie Babies were two of the most popular FADS of that era. Pet Rocks were small, smooth stones that were sold in cardboard boxes with air holes and a straw bedding. They became popular as a novelty item and were often given as gifts. Beanie Babies were small, stuffed animals that were made of fabric and filled with plastic pellets. They were also popular as collectible items and were often traded among friends. Both Pet Rocks and Beanie Babies were short-lived FADS that have since faded from popularity.
