#1 TOP DEFINITION
심쿵 — heart flutter. From 심장 (heart) + 쿵 (thud sound). The feeling when an idol does something unexpectedly sweet, charming, or attractive and your heart drops. One of the most common reactions to idol content — used for everything from a casual smile in a vlog to a breathtaking stage look.
Example
“Taehyung's candid airport photo — no styling, just glasses and a sweater — caused absolute 심쿵 across all platforms.”
