고구마 (goguma) — A frustratingly slow or stuck situation.
Lesson 52 in our Korean Slang series, adapted from Korean Your Teacher Doesn’t Teach You by Injin Hwang. This expression appears in the book’s fandom and entertainment section.
What 고구마 means
In a drama review, 고구마 전개 suggests that characters cannot say or do the obvious thing, leaving viewers impatient. The situation and tone help determine how natural the expression sounds.
A short conversation
A: 주인공이 또 오해를 안 풀었어.
B: 아, 고구마 전개네.
A: The lead still did not clear up the misunderstanding.
B: What a frustrating plot.
Use it with care
The literal meaning is sweet potato. In this figurative use it evokes the stuffy feeling of swallowing one without a drink; context tells you which meaning is intended.
A neutral or polite alternative: 전개가 답답해요. — The plot feels frustrating.
Try it yourself
If a friend says 고구마 전개, are they ordering food?
Answer: No. They are criticizing a slow, frustrating plot. Read the Korean exchange aloud, then replace one detail with something from your own life.
