I learned that term "Schadenfreude" long long time ago during Psychology 101 class.
Tthis term is typical of the mentality of 五毛 or some of the 憤青 on LYK...especially the one with 精神分裂症.
Very limited in dictionary and wording ever known to them: always resort to using "jealous" this, "jealous" that, blah blah blah.
Fact is: since none of the rest of LYKers share their enthusiasm to begin with, then their pride/postings are nothing to us really. Guess what: a single hand cannot clap and will become lonely eventually....
