Whenever coming across this word in a description of a Korean woman, I always found it just a tad strange. Right now I haven’t got the faintest clue how I and my language partner even got to talk about this so let’s just get to it. Basically the word comes from two different parts:
꿀 ~ honey
허벅지 ~ thigh
When combining the two words, the 허 is dropped so that the combined word reads 꿀벅지.
It is used about young women who have slim legs, but who are not downright skinny. More of a healthy-firm/slender type of leg – by Korean standards, which may of course vary from other corners of the world.
The singer-gone-actress UEE has been often been associated with this particular term, although, apparently she might not have honey thighs anymore…
I’ll end here before this post gets too odd…
