“AFK” stands for “away from keyboard,” a quick way to tell people online that you have stepped away from your computer or device. It signals that you may not see messages or respond for a short time. The term is a staple of chat apps, online games, and workplace messaging.
What does AFK mean?
AFK is an initialism built from the first letters of “away from keyboard.” When you send it, you are letting others in a chat, game, or channel know that you are temporarily not at your device. It is a courtesy that manages expectations, so people understand why you have gone quiet and do not assume you are ignoring them.
Where did AFK come from?
According to Grammarly and Wikipedia, AFK developed as a piece of chat-room etiquette in the 1990s, when Internet Relay Chat (IRC) was popular. Users typed it to explain sudden silences. It was then widely adopted by the gaming community, especially in massively multiplayer online games, where letting teammates know you are stepping away matters for coordination. Sources note it is not certain whether the term first appeared in chat rooms or gaming, but its mainstream spread is strongly tied to online games.
How do you use AFK?
AFK works as an adjective or a standalone status. People often pair it with other shorthand such as “brb” (be right back). Typical examples include:
- “brb, afk for a few minutes.”
- “I’ll be afk during lunch.”
- “Sorry for the slow reply, I was afk.”
- “He’s afk, so start without him.”
Does AFK have other uses?
In gaming, “AFK” can also describe a player who is present in the game but not actively participating, sometimes called being “AFK” at the keyboard. In some multiplayer games this can be a problem, and “AFK farming” or “going AFK” mid-match may even carry penalties. Outside of games, the term has broadened into general internet slang, and some people now use “AFK life” to refer casually to time spent offline and away from screens.
Is AFK still used today?
Yes. While it grew out of early chat culture, AFK remains common across gaming, group chats, and even office collaboration tools where status updates are useful. It is informal, so it fits casual and semi-casual settings rather than formal writing. Its meaning is stable and widely understood: you have stepped away, and you will respond once you are back at your keyboard.
It is also worth knowing a few close relatives. “BRB” (be right back) is often used alongside AFK, while “AFK” specifically stresses that you are physically away from your device. Some communities use “BAK” (back at keyboard) to announce a return. Together these small phrases form a shared etiquette that keeps online conversations and games running smoothly even when people step away.
In short, AFK is a compact, long-lived piece of internet shorthand. It communicates a simple but useful message, that you are temporarily away, and it has carried that same meaning from 1990s chat rooms to today’s games and messaging apps.
