right-facing fist

It's a right-facing fist. It's mainly used to express greetings, promises, or friendship.

It's commonly used as a greeting called "fist bump" among young people these days. It has gained more popularity especially after COVID-19 as an alternative to handshakes.

This gesture originated as a symbol of solidarity in the American Black civil rights movement in the 1960s. It later spread globally through sports, hip-hop culture, and more.

In modern times, it has become a casual greeting for the MZ generation and is frequently used in online games or esports culture to signify victory or cooperation. It's also popular as a fan service gesture by K-pop idols.
