A fad refers to a trend or craze that becomes popular for a short period of time. It could be a fashion trend, a popular dance move, a type of diet, or any other kind of activity that people start doing suddenly and out of nowhere. Fads usually fade away quickly and lose their popularity in a few weeks or months. Examples of fads include the "Harlem Shake" dance trend, the "Ice Bucket Challenge" charity trend, and the Atkins diet craze.
