AFK
Abbreviation · Slang & Abbreviations · Origin: 1990
Definitions
AFK stands for Away From Keyboard, an internet abbreviation indicating that someone is temporarily unavailable or not at their computer. The term originated in early internet relay chat (IRC) and online gaming communities in the 1990s, where it served as a quick status indicator for other participants. In multiplayer games, going AFK can be particularly disruptive since the absent player character may be left vulnerable or their team may be short a member. Many online platforms and games now have automatic AFK detection that marks idle users, kicks them from active sessions, or places them in a spectator mode. The term has expanded beyond its literal meaning and is sometimes used casually in everyday conversation to mean temporarily unavailable, even in contexts that do not involve a keyboard at all.
In plain English: A way to tell people in a chat that you've stepped away from your computer and can't respond right now.
Extended to describe a lifestyle or philosophy of deliberately disconnecting from screens and digital communication. 'Going AFK' can mean a five-minute break or a two-week digital detox, depending on your burnout level.
Example: 'I'm going AFK this weekend — no Slack, no email, no pull request reviews. The codebase will survive without me.'

Origin Story
The Three Letters That Meant You Stepped Away
AFK, meaning 'Away From Keyboard,' emerged in the early 1990s from the vibrant text-based online communities of IRC (Internet Relay Chat) and MUDs (Multi-User Dungeons). In these real-time chat environments, other participants could not see you and had no way to know if you were sitting at your computer or had wandered off to make a sandwich. Typing 'AFK' became the polite way to signal your temporary absence so others would not wonder why you were not responding. The abbreviation is among the earliest internet-native slang, predating the World Wide Web's mainstream adoption. It spread alongside other chat acronyms like BRB (be right back), LOL (laughing out loud), and BBS (be back soon). MUD culture was particularly formative: in text-based role-playing games, going AFK could get your character killed by monsters, so announcing your absence was a survival strategy as much as a courtesy. As the internet moved from chat rooms to social media and mobile messaging, AFK took on a broader meaning. It evolved from a literal keyboard-absence notification to a general term for being offline or unavailable. Gamers, streamers, and remote workers all use it today, and it has even crossed into spoken language.
Context: IRC and MUD communities, early 1990s
Fun fact: In some competitive online games, going AFK is a punishable offense. League of Legends, for example, can temporarily ban players who go AFK during matches, treating it as a form of unsportsmanlike conduct.
