Oh, look, I found the word 단호박 (a Korean slang)!
This is from a video uploaded this morning on BTOB’s V Live channel: http://www.vlive.tv/video/22176?channelCode=FD737 (with hangul script for learners).
Changsub said to Sungjae: 솔직히 말해. 나 존경스럽지? (Just say it, honestly. I’m worthy of respect, right?)
Sungjae answered: 아니. (Nope.) in a 단호박 manner.
HyunWoo 선생님 taught this word for Korean Buzzword section on Arirang Radio. The word 단호박 could mean ‘sweet pumpkin’/’autumn squash’ that taste sweet, but as a slang, it means a person who says no really quickly without even trying to be soft about it, or the act of refusing flatly. It’s from the word 단호하다 (to be firm, resolute).
Reference: Open Dictionary for Korean Buzzwords “우리말쌤”: 단호박 http://me2.do/xX3um2EJ (in Korean).
To say to a friend who said 아니 (no) to your invitation or question:
‘너 완전 단호박이구나.’ or just ‘단호박.’
(You’re very straightforward when you say no).
Isn’t it amazing that after you learn a Korean word, it suddenly appears everywhere? Just like HyunWoo 선생님 said on Hey Korean: 아는 만큼 보인다 (what you know determines what you see). ###
