The Korean nationalistic phenomenon is equivalent to being "drunk in one's victories." Nationalistic Koreans love to dwell on trivial achievements and victories, they HAVE to rub it in your face that Koreans did this, did that. For example, it's 2008 and I still hear Koreans talking about how S. Korea advanced "so far" in 2002's world cup. The Dutch surrogate coach made that possible, because it wasn't a Korean coach.
non-Korean: You're a delusional brash Asian bumpkin, and a victim of Korean nationalism. Hey, by the way, your breath stinks, I think that kimchee chigae or dog-meat stew you ate did it.
Korean FOB: what muda-phukaa???? I phuck you up, I'm taekwondo master. koh-rhee-uuhh izuuhh bestuuhh!!!!!!
