Slang.

[ksuechuelam]

I think it might be somewhat useful to know some slang... perhaps common expressions used between friends.

Also, other expressions that might indicate someone is really pissed off with you would be helpful. (swearing)

Haha, you're right.... though I think if watching Korean movies, dramas it will stick expressions and some swearings as well....

Try working in an all Korean auto repair facility for a month or two...

Really, the bad stuff will come naturally.. learn the good stuff first.

One thing I really love about Korean is that the first words I learned were not curse words.. unlike several other languages I have been exposed to.

I think Korean may be the first language ever where calling someone a human being "저 인간" is impolite.

I almost feel bad for posting my collection of bad words. Please use this carefully - meaning don't use them but know what they mean of someone uses them. Curses, Insults, Being Rude. For more of just everyday slang that isn't so harsh, Colloquial Phrases compilation might be more appropriate.

hope it helps!
