Refers to nigga cootie
war, from the famous kpop song singing Korean that sounds "nigga cootie war, poggers butthole".
This is a way of using the n word without getting criticized since you can just say you are speaking Korean, but really you are just saying the n word. Nigga just means "you are" in Korean.
If you use it enough, your
friend might join you to sing "poggers butthole". Which is the sequel of this amazing sentence and you and your
friends can get away with anything ;)
