In chinese, there’s an expression for this….Probably I’m misspelling it, but it’s called “nai pi”.
(Ni hen nai pi) (you are very ….)
An expression that conveys the notion that someone is a sore sport. Perhaps someone else can do a better job translating (I flunked the pinyin system).
Anyway, lot of people these day fit into this category. Not living up to one’s obligation and taking the legal (but crass) way out.
