3 Words in Running Man Ep. 293(수상한 봄나들이, Majority Decision Race)
It's the shortened phrase of "심장이 쿵 하다".
심장 is your heart. 쿵 is the onomatopoeia for the sound of hard object hitting against another hard object. It is usually used when something big on the table fell off to the floor. So, 쿵 하다 means hitting something hard.
When you meet your ideal type, your heart will race. This heart race is called 심쿵 in Korean. If you are a fan of KPOP, you might have heard of the song, 심쿵해, by AOA.
