Etymology

Origin of fad

1825–35; noun use of dial. fad to look after things, busy oneself with trifles, back formation from obsolete faddle to play with, fondle. See fiddle

Explanation

If it’s all the rage, everybody’s into it, your parents don’t get it, and teenage girls across the globe are trying to outdo each other with it, it’s officially a fad. From hairstyles to hula hoops to saying “that’s hot,” fads are known to rise to crazed levels of popularity seemingly overnight. But they fade out just as fast, leaving late adopters with outdated sayings and some seriously uncool shoes. Much like a fad itself, no one has any real idea where this word came from. But it’s still in fashion some 144 years later.
