Omega is the last letter of the Greek alphabet. An omega male then is the "last" man. In essence, if you were to rank all the men in the world by their virtues (bravery, intelligence, leadership, generosity, etc.), an omega male altogether would be the worst, hence "last," of all men.

Omega是希腊字母表中的最后一个字母。因此，omega male自然指的就是男人中排在“最后一名”的人。也就是说，如果要给全世界的男人按照勇敢、智力、领导能力、慷慨程度等优点排名的话，omega male肯定是排名最后的。因此，这里译为“绝世衰男”。

Typical omega male traits include an intense interest in a particular hobby, which consequently draws his time and energies away from the conventionally 'important' things in life, like work or romantic relationships. The omega male is a fun-loving but non-aspirational individual who is reluctant to 'grow up' by embracing classic social imperatives like marriage, family and holding down a regular job.

典型的“绝世衰男”特征包括：沉迷于某个爱好，因此把大量的时间和精力花在这个爱好上从而忽略了工作、爱情等生活中一些重要的事情。他们喜欢玩乐，但并不渴望有所成就，他们不愿意按照结婚、成家，以及有个稳定的工作等传统的社会标准来当个“大人”。

This often-unemployed, romantically challenged loser can show up as a perpetual adolescent, or a charmless misanthrope, or a happy couch potato. He can be sweet, bitter, nostalgic, or cynical, but he cannot figure out how to be a man.

这些衰男时常处于失业状态，感情发展也不顺利。他们有时像永远长不大的孩子，有时又是个惹人厌的愤世分子，有时又躺在沙发上盯着电视傻乐。他可以是甜蜜的、苦涩的、忧愁的，或者愤世的，但他似乎总是不知道该怎样做个真正的男人。
