The Finger heart, also called Korean finger heart gesture, is a trend that was popularized in South Korea since 1990s, in which the index finger and thumb come together like a snap to form a tiny heart.[1][unreliable source?] The gesture was popularized by K-pop idols, who would often use the gesture to express their love and gratitude to their fans. It is represented in Unicode with the codepoint U+1FAF0 🫰 HAND WITH INDEX FINGER AND THUMB CROSSED as "Hand with Index Finger and Thumb Crossed".
