“Everyone studying language desperately needs this kind of book; the kind of book that teaches you how people REALLY use the language. And while slang is not entirely academic, it is far more communicative and useful for engaging in a new language than the stilted artificial bullsh*t textbooks normally stuff down the throats of learners. With the goal of teaching the wonderfully versatile and totally day-to-day relevant slang that will allow you to be welcomed into the culture, we are delivering the secrets of the street; the true language of Seoul; and helping you understand how Koreans think, act and speak!”
