Someone who is obsessed with Korean culture so much they denounce their own culture and call themselves Korean. They usually are kpop fanatics (not fans) or fans of League of Legends or other competitive games popular in South Korea. However there is a line; if someone just likes the music, language and culture they are not classed as a koreaboo.
"That boy over keeps calling himself Korean and all he talks about is Korean things, he's such a koreaboo!"
