Someone who is obsessed with Koreans/Korean culture. (and isnt korean) That person might even try to learn Korean, make a korean name for themselves, and indulge themselves on anything korean like music (Big Bang, BoA, se7en, epik high, Rain, Wonder Girls), dramas (My Sassy Girl, Il Mare, Windstruck, JSA, A Millionaire's first love), food (Soju, kimchi, bul-dak, tang-su-yuk), etc.
Also, the person will be obsessed with Korean celebrities (for example, Rain Bi, Jyeon Ji Hyun, Seung Ri, Ji Woo Hyun, etc) and will want their significant other to be Korean.
