Favorite Korean words/expressions?

I like words that are several words shortened into one single word haha, like 깜놀 which means "what a surprise", or when you're shocked, and is a shortening of 깜짝 놀라다, and 엄친아 means mum's friend's son, meaning someone who's perfect, and it's a shortening of 엄마 친구 아들. I also like it when they say English words but in Korea, so konglish, like 레알 :D

My personal favorites are 죽을래 [jugeullae] (wanna die?) and 그래서 [geuraeseo] (so what?), but I caught myself saying 아이씨 [aissi] (popular "aish") and 아이고 [aigo] (you know that :P) ALL THE FREAKING TIME, I wonder what strangers think of me when I shout these things out loud...

 aish, aigoo, jinjja, jen-jang ...  Usually said when something goes wrong for me!

I caught myself smilling while reading all your post..because i do the same, its just came out on lips whenever im with my friends..
