I've posted before on Japan's grass-eaters or herbivorous men, who wear make-up, are not ambitious at work and aren't very interested in women. South Korea has its own herbivores too, as I read recently in an article by the Financial Times' Korea correspondent (here). These are dandy metrosexuals, according to the article, who prefer to drink wine or soft drinks, and don't like martial arts, much to the disgust of their rather macho elders.
Dried-fish women are young women whose social life consists of lying on the sofa, watching television while eating dried fish. Both they and the herbivore men are loners in a society that is traditionally collectivist, and they have both shunned the traditional Korean life path of education, marriage and family.
