My favorite Korean words/phrases

Lately I've been studying vocabulary and I've come across a lot of interesting expressions. I came across most of these words in vocab lists, not in actual use, so I wouldn't be surprised if some of them are old-fashioned or rare. But I like all of them either because of the meaning or just because of the way they sound. In some cases, I'm intrigued that the language has a word for certain specific concepts.
