Post-Adolescent Idealistic Phase is the time after the pointless teen years in which a young person develops what are called "standards" and "morals". It is a time in which eyes are opened and "The Truth" suddenly becomes clear.

后青春期理想主义阶段（Post-Adolescent Idealistic Phase）指经过混沌无知的少年时光之后，年轻人开始萌生“标准感”和“道德感”的一个时期。这是让他们大开眼界的时期，“真理”也会突然变得明晰可见。

The Post-Adolescent Idealistic Phase usually entails naive 18-20something year-olds upholding hopeful, yet unrealistic morals. Often, utopian dreams can be confused for "The Truth."

后青春期理想主义阶段多见于18到二十几岁的天真青年，他们都秉持一些带给人希望但又不切实际的道德观念。他们通常会把乌托邦式的梦想与“真理”混为一谈。

Usually beginning when one enters college, these young persons read deep literature, listen to college radio, and search for the meaning of life, all the while secretly becoming even more confused than when they were lame 16 year-olds.

从进入大学开始，这些年轻人开始读深刻的文学作品，收听大学电台，并且寻找生命的真谛，而与此同时，内心深处却比懵懂的16岁那会儿还要困惑。

After the phase has ended, the young person must beware of becoming highly hypocritical and/or jaded once life has slapped them around a bit. (Source: urbandictionary.com)

这个时期过后，这些年轻人可能会因为受到生活的打击而变得非常愤世嫉俗或者意志消沉。
