미쳤다 (michyeotda) — Unbelievably good; that is wild.
Lesson 11 in our Korean Slang series, adapted from Korean Your Teacher Doesn’t Teach You by Injin Hwang.
What 미쳤다 means
Friends may say 미쳤다 when a high note, performance or view feels almost unreal. In this lesson it is exaggerated praise, not a literal description of someone’s condition.
A short conversation
A: 이 노래 고음 들어 봐.
B: 와, 미쳤다.
A: Listen to that high note.
B: Wow, that is unreal.
How to understand the expression
미쳤다 comes from 미치다, but its positive meaning depends heavily on context. 와 and an admiring expression help signal praise. The same words in an angry voice could communicate criticism. Learn to recognize the whole situation rather than treating this as an all-purpose replacement for 좋다.
Use it with care
Very informal and emphatic. Avoid labeling a person with it or making jokes about mental illness. For a teacher, unfamiliar performer or formal comment, ordinary praise is clearer.
A more neutral or polite alternative:
정말 대단하네요!
That is truly impressive!
Try it yourself
Does 미쳤다 always express praise?
Show the answer
No. Context and tone determine whether it expresses admiration, disbelief or criticism.
Read the conversation aloud, then try the neutral alternative. Notice how the relationship between the speakers changes which wording feels appropriate.
