세상에 뭐 이런 단어가 다 있어. 제주도도 아니고 제준이형도 아니고.
From Oxford dictionary @ mac os x
- naive, simplistic, and superficial : their entirely predictable and usually jejune opinions.
- (of ideas or writings) dry and uninteresting : the poem seems to me rather jejune.
ORIGIN early 17th cent.: from Latin jejunus ‘fasting, barren.’ The original sense was [without food,] hence [not intellectually nourishing.]
