In case anyone wants to know where it came from, the Korean word for “Korea” is “한국,” pronounced han-gook. “Gook” is actually the general word for country. “Mi-gook” is America (literally “beautiful country” when written in Chinese characters 美国, following the Chinese Mandarin “meiguo,” which also means “beautiful country).” China is “Chun-gook,” Thailand is “Tae-gook,” and so on. Other countries don’t follow the rule like Japan, Germany, France, a lot of it is historical happenstance.
Hmm - Hankook Tires? (I thought it might mean “open Country” or something. I searched and found that Hankook means “Korean” - so Korean Tire Company).
