Updated 6 October 2026
BRB means “be right back”: a note that someone is leaving the chat briefly and will return soon.
What BRB can mean
1. I’m stepping away for a moment
The standard meaning. Someone is at the door, making tea, answering a call. “brb, kettle” tells the other person to wait a couple of minutes, not to assume the conversation is over.
2. A polite exit that may not return
Sometimes “brb” is a soft way to leave a conversation that has run its course. If the person then disappears for hours, that is usually what happened, and nothing personal is meant.
How people use it on Instagram and Facebook
DMs
Typical in a live back-and-forth: “brb, door.” The other person usually answers “ok” or a thumbs-up and waits.
Group chats on Messenger
Used when several people are chatting at once, so the others know someone has left for a minute rather than ignored a question.
Live videos and streams
A creator who types “brb” in a Live chat is warning viewers about a short break. Since nobody sees a screen, it is a way to hold the audience.

How to reply to BRB
Where it comes from
BRB comes from the early days of online chat, where typing was slow and people needed a fast way to say they had left their keyboard. It sits in the same early-internet family as AFK (“away from keyboard”) and TTYL (“talk to you later”).
Questions people ask
How long is “right back” meant to be?
A few minutes, in theory. In practice “brb” stretches, and many people say it for anything from two minutes to half an hour. If it matters, add a time: “brb, 10 mins.”
What is the difference between BRB and TTYL?
BRB means the person is coming back to this same conversation soon. TTYL (“talk to you later”) closes the conversation for now with no promise of when.
Should I say BRB to a customer?
It is fine in a live chat, but remember that on Instagram and Messenger a business can only message someone within 24 hours of their last message. If your “brb” becomes a long gap, send a proper reply before then.
Is BRB too old-fashioned now?
Some younger users find it dated and write “one sec” or “gimme a min” instead. It is still understood everywhere and nobody will mind it.
