How do you say "Im procrastinating" in korean?
For example
"I'm supposed to be doing my homework but I'm putting it off"
is it 내가 꾸물거리다? or is that unnatural/incorrect?

Question

Answer

In that case,the word "lazy" is more like it.
뭔가 해야 할일을 자꾸 미루고 있으니 "나는 게으르다"는 표현이 적당.
On the other hand "꾸물거리다"는 어떤 특정 시점(at a certain point) 뭔가를 천천히(굼뜨게) 하는행동을 말함.
예를 들면,1.그만 꾸물거리고 빨리가자,안그러면 버스시간에 늦겠다.2.신문 좀 가져오라고 하는데 뭘 그렇게 꾸물거리고 있어? 빨리 좀 가져와!

Hope that helps!

Answer

maybe 질질 끌다 would be apt to describe that...

it is kind of like dragging your feet (sluggish to act) over something
