too expensive than its value
If a bag of snacks has just little snacks and almost air in there, we say 창렬하다. 창렬 means a Korean singer 김창렬(Kim chang-ryeol). He allowed to use his name to a food company and lunch packs named his name produced. But the lunch packs had very small amount of food and the rest of them was empty. So, people say his name for standing for this kind of unfair situation.
이 과자는 너무 창렬하다. 양이 얼마 없네.
