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!"

Someone who denounced their own race and calls themselves Korean, genuinely believes that they’re Korean or wishes they were Korean. They may also think that they will some day marry their favourite idol (see also delulu) or may use small parts of Korean in their sentences without caring about learning the language. They could think that all Asians/Koreans are beautiful gods who are above the human race (see also yellow fever).

Not someone who:
-is interested in Korean culture
-listens to Kpop music
-listens other Korean music genres
-watches Korean TV shows
-makes cringey jokes about Korean celebrities
-wants to live in Korea
“Jackie is such a Koreaboo, she’s American she shouts ‘OPPA’ at random Asian men and tries to look Korean by glueing her eyelids down.”

Someone who is obsessed with Korean culture (not north, but south) and talks about them non-stop. Probably won't see them ever again, because while you are reading this, they have immigrated to Seoul.
Why are you such a Koreaboo! I'd rather you be a weeaboo!

1. A person who wants to be Korean by listening to k-pop, using the Korean language in the wrong way, and disrespecting REAL Korean culture.

2. A very shitty website that serves almost no real purpose, only that it shows news about k-pop and just about nothing else "Korea" related

A website that posts inaccurate stuff and starts fandom wars in the Korean music industry.
Only thing Koreaboo knows how to do is source from "Netizens".

Koreaboo posted another bullshit headline again.
