‘Fads’ refer to some kind of behavior or situation wherein a significant part of a group of people, for example, is overly enthusiastic about something for a certain period of time.  Usually fads last for a short period only, or at least until most people get to see or experience a new thing or craze.  Fads are also expected to disappear for the simple reason that people’s enthusiasm over a lot of things will eventually wane.  Some people also get to experience new things and move on from one fad to another.  There are people also who realize that certain fads are not worth hanging on to but would rather make themselves feel happy to move on.

时尚可能有不同的形式。其中一种形式涉及服装和配饰。世界上许多人已经体验过最酷的服装、本季最受追捧的鞋子或是最棒的小玩意等时尚。在时尚之初，许多人会渴望购买流行或最新的东西。例如，在小玩意方面，人们可能渴望得到具有最佳功能和独特设计的最新手机。拥有这样一部手机会让人们感觉很有力量或者很时髦。但一段时间后，人们也会习惯于拥有据称是世界上最酷的手机。随着新款手机的问世，或者人们意识到，使用其他基本型号的手机会更好，人们对这款手机的兴趣很快就会减弱或消失。这种时尚也可以应用于人们对最喜欢的食物、最新的运动狂热、最时髦的都市行话以及其他许多事物的感受。

然而，不管形式如何，许多时尚会在一段时间内一个接一个地消失。有些时尚可能会持续几个月或几年，但人们的兴奋或热情将无法持续，最终这些人中的许多人将对某一特定时尚失去兴趣，转而从事其他事情。
