A crazy hardcore fan of Korean stuff who even denounce their own culture and call themselves Korean. So basically A disgrace to Koreans and their own culture and their parents. And people that just like Korean drama, their food, Kpop songs, etc are not considered Koreanboos so don't go calling people who are normal fans who like those stuff Koreanboo you will likely be laughed at.
Note: My English is not very fluent so I am sorry if there are any mistakes.
Guy 1: Yo one of my classmates is CRAZY about Korean stuff she yells "OPPA!" every time she sees Asian men! like with no shame!
