Brb
BRB is internet shorthand for 'be right back,' typed into chat rooms and group threads to flag a short pause in the conversation. The three-letter initialism goes back to at least a January 1989 chat log from an Apple II Development Forum and moved through Usenet, IRC, MUDs, and AOL Instant Messenger across the 1990s and 2000s.
Overview
BRB is a three-letter internet abbreviation for the phrase 'be right back,' typed into chat rooms and group threads to note that someone is stepping away for a moment. It sits alongside AFK, IMHO, BTW, FYI, FWIW, OTOH, and WYSIWYG in the small vocabulary of chat shorthand that Usenet posters were already listing off for newcomers in the early 1990s1.
The word almost always signals a short break rather than a full exit. Someone who types brb in a group DM is telling the room to hold the thread, not to close it. Urban Dictionary users have logged dozens of definitions since 2003, most of them agreeing on the 'leaves briefly, returns shortly' reading, with plenty of jokes about the friend who types brb and never actually comes back6.
How It Spread
How to Use This Meme
BRB works as a quick heads-up in any real-time chat: type it, step away, then come back and rejoin the conversation. Common practice is to add a short reason after the letters, like 'brb dog' or 'brb food,' so the rest of the group has a rough sense of how long to wait6. Some people type 'b' or 'back' when they return, though a returning message is optional. The abbreviation reads the same in lowercase or uppercase, and dropping it into a slow-moving thread like email or a work channel is usually read as a joke rather than a real away signal.
