How to say im dying of laughter in korean?
I want to know how to say I am dying of laughter in korean. 
Also I want to say I can't stop laughing. I know 웃다 is to laugh and 멈출 수 없다 is to can't stop but how do I add a verb in front of it?

Answer

I am dying of laughter: '나 웃겨 죽겠다'

I can't stop laughing: 웃다 + 멈출 수 없다 = 나는 웃음을 멈출 수가 없다 ( but more natural to say '나 웃겨 죽겠다')

Answer

koreans are used to say this way.
Im dying of laughter 너무 웃겨서 죽을것 같아요
I can't stop laughing 너무 웃겨서 웃음을 멈출수가 없네.

Answer

1. I'm dying of laughter  = 웃겨 죽겠다. 
2. 웃음을 멈출 수 없다. 웃다 = verb , 웃음 = noun
   (나는) 웃음을 멈출 수 없다. -> 웃음을(object) + 멈출 수 없다 (verb)
