I have a feeling this is the book Sebastian was referring to: "Me han dicho, que en el Kyobo Bookstore se puede comprar un libro sobre frases hechas koreanas con explicaciones en inglés... Desafortunadamente no sé koreano." [I've been told you can buy a book on Korean set phrases from Kyobo bookstore. But unfortunately I don't speak Korean.]
Although I disagree with some of the transliterations in the book and most of the phrases come across as being rather negative, aggressive or resigned, it's a good collection. As usual though, the best way to pick up phrases/idioms like these is probably to actually talk to Korean speakers themselves.
