智能手机让很多人全天候都挂在网上，更新微博，看朋友圈的动态，或者看看自己所在的小组最近有什么活动可以参加。他们最怕错过新鲜八卦。如果有一两天没有上网看这些，他们会感到自己已经“与世隔绝”太久了。

　　Fear of missing out or FOMO is "a pervasive apprehension that others might be having rewarding experiences from which one is absent". This social angst is characterized by "a desire to stay continually connected with what others are doing".

　　“害怕错过”(常缩写为FOMO)指的是担心自己缺席时，其他人会获得有益体验的一种普遍的忧虑情绪。这种社交焦虑的特点是“希望一直知晓其他人在做什么”。

　　FOMO is also defined as a fear of regret, which may lead to a compulsive concern that one might miss an opportunity for social interaction, a novel experience, profitable investment or other satisfying events.

　　“害怕错过”还可以定义为一种遗憾，这有可能导致一种强迫性的关心，比如担心自己可能错失了一次社交机会，一种新奇体验，一项有利可图的投资，或者其他让人满意的事情。

　　Besides its impact on real-world social activities, FoMO could also influence the formation of long-term goals and people's self-perceptions.

　　除了对现实生活中社交活动的影响，“害怕错过”还可能影响长期目标的形成以及人们的自我认知。

　　例句：Even though he was exhausted, John's fomo got the best of him and he went to the party.

　　尽管感到非常疲惫，但约翰心中“害怕错过”的情绪还是占了上风，他最终参加了聚会。
