A fad is something that has temporary popularity. Fads are often started among teenagers, but adults also participate in the creation of a fad. There are fads in clothing, dieting, vacationing, and other activities that seem to change over time.
Tanya avoids clothing fads when buying her clothes. She’s very conservative.
My friend, Matt, wears a hands-free device in his ear when talking on the phone, but most people think of this as a silly fad.
Low-carb diets were a fad a few years ago. Now gluten-free diets are popular.
The wearing of sagging pants by teenage boys is a fad that hopefully won’t last much longer.
Beanie Babies were a fad ten years ago.
In the 1970s, mood rings and pet rocks were fads that made their creators very rich.
Most fads come and go, but sometimes they remain popular enough to become a lasting part of the culture.
