You definately need this book.... Making Out In Korean Its an amazing guide to everything from Insults and slang to making love and partying in Korean, with written korean and phonetic translations, i bought it a couple of months ago and it well made me laugh!
this makes me remind my teen age years... when my Taekwondo teacher used to swear in korean. Mainly, he used to call us like: ee-sae-kia!!! lol.
