1. North Korean dictatorship lol, not because it's dictatorship but because it is not a successful implementation.
2. Daebak (대박), not exactly the word but excessive use of it. It's so random it annoys the heck out of me. Also wooo~ used alongside it. Like why would you go on daebak×∞ for some rice and pot of soup? These two words were so annoying that I asked a Korean person.
Korean person said both words are used often but the reason they annoyed you is because the persons speaking it are trying to act excited when they are not and they are terrible actors and it doesnt sound this fake and annoying in general. Those People were few popular kpop idols, I won't name them. Also i was told usually you can use woo~ or khaaa (screeching sound) when you like something, could be used for something you dislike as well.
What are the things you guys don't like?
