Left-Facing Fist

They're offering a fist bump; send 🤜 back and it's complete. After your good news it is a quiet well-done, after a plan it means «deal», after a joke or a shared opinion it means «same». It is the emoji version of two people touching knuckles, the small greeting that friends, teammates and colleagues trade instead of a handshake. Your reply is 🤜, so the two fists face each other: 🤜🤛. Put them the other way round, 🤛🤜, and they point apart.

The tone is casual, friendly and a little sporty. It doesn't carry the affection of a heart; it says «good job, mate» at arm's length, which is exactly why people use it with colleagues and acquaintances. Where it can misfire is on its own in a heated exchange, where a clenched fist is still a clenched fist and some readers take it as a threat. A word beside it, or the pair, settles that.

What is a fist bump, and where does it come from?

Two people lightly touch knuckles instead of shaking hands. You see it between baseball and basketball players after a good play, between friends greeting each other, and as a low-key «well done» in many settings. Its best-known roots are in Black American culture: dap, a word first recorded in 1971, was an elaborate handshake-and-knuckle greeting among Black U.S. soldiers in Vietnam, a sign of friendship and solidarity, and it can include a fist bump. The plain bump, also called a pound, became a fixture of sport and everyday life; nobody can name a single inventor, and several rival origin stories circulate.

Emoji already had 👊, a fist coming straight at you, and the raised ✊, until a 2015 proposal added 🤛 and 🤜 as a pair for exactly this picture: two sets of knuckles meeting. The gesture had a second moment during the COVID-19 pandemic from 2020, when handshakes were discouraged and the fist bump and the elbow bump became popular substitutes.
