The mini heart gesture is a trend that was popularized in South Korea in which the index finger and thumb come together like a snap to form a tiny heart. 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 symbolized in Unicode by the codepoint U+1FAF0 under the name “Hand with Index Finger and Thumb Crossed.”
The thumb and index finger gesture, popularized by K-pop and Korean dramas in Asia, is gaining global recognition through the influence of the Korean Wave. In K-pop, notable figures like G-Dragon, PSY, and bands such as EXO and BTS have introduced this gesture to a broader international audience.
