Xenonationalism
Having or possessing intense or above average nationalistic feelings for a country not of one's heritage, cultural background, or citizenship to the extent of which the person is willing to do the same that someone who feels patriotic for their own country would do for another country
Bob is very anti-patriotic he has very xenonationalistic feelings for Korea.This xenonationalism sure is weird I wonder how anybody can feel so much for another country and not their own.
