중꺽마

중꺽마 (Jung Kkuk Ma) 

중요한 건 (Jung Yo Han Gun) important thing  
꺽이지 않는 (Kkuk E G ahn Neum) do not give up 
마음 (Ma Eum) mind, Thought 

The most important thing is a heart that does not give up.

However, when a heart that does not give up is used even though the game has already ended in defeat, it is also used for sarcastic purposes.
