How do I say," you're in trouble!" Like a school teacher scolding you in korean?

Question

How do I say," you're in trouble!"  Like a school teacher scolding you in korean?

Answer

"You're in trouble!" => 넌 혼 좀 나야 돼 [해]! / 너 혼 좀 날래? / 너 벌 좀 받아야겠다!

- 혼나다/혼이 나다다: get a scolding from a teacher, parent, etc; have a punishing hard time.
- 혼내다/혼을 내다: scold someone.
- 벌(을) 받다:  be punished (벌 = punishment). 
- 벌(을) 주다:  punish someone.

* 혼 means "spirit", so 혼내다 literally means scolding severely enough to get the spirit out of him.
