Bro Fist
Bro Fist is internet slang for the fist bump greeting, best known online as an ASCII copypasta of a clenched fist that spread through 4chan, DeviantArt, and FunnyJunk starting in October 2008. YouTuber PewDiePie later brought the gesture to a wider audience through videos featuring bro fist sign-offs and street fist bumps.
Overview
Bro Fist is internet slang for the fist bump greeting, where two friends tap closed fists together to say hello or celebrate a moment4. Online, the term is tied to a specific ASCII copypasta drawn to look like a clenched fist, made from slashes, dots, and parentheses, which spread on forums and message boards as a reply people pasted to greet each other4. The art is often accompanied by a chain-letter style dare like 'bro fist if you don't post this to five other bros you're not a bro'4.
Off the internet, the fist bump has a longer history that the meme borrows from. The St. Louis Post-Dispatch has floated St. Louis Cardinals player Stan Musial, who played in Major League Baseball from 1941 to 1963, as a possible inventor of the informal version of the greeting1.

How to Use This Meme
The ASCII copypasta is typically pasted as a standalone reply on a forum or dropped at the end of a supportive comment, treating the reader as a 'bro' being greeted. In photo and video form, people often stage a fist bump toward the camera or another subject, with the caption 'brofist' or 'bro fist' doing most of the joke work4.
