What does BRB mean?
BRB means “be right back.” It is a short signal that you are leaving a conversation for a moment and will return soon. The point is to avoid confusion. Without it, the other person may think you have lost interest, lost your connection or ended the chat.
A BRB is really a small promise. The word “right” in the phrase suggests the break will be short, usually a few minutes.
Where does BRB come from?
BRB dates back to the early days of online chat, in the 1980s and 1990s, when people talked in text rooms and bulletin boards. Typing was slow, and people were often on dial-up connections. Short forms saved time and told others why a person had gone quiet. BRB became so common that it jumped from computers to phones and even into spoken English, where some people say the letters out loud as a joke.
How people use BRB
In texts and chat apps
Friend: Are you coming tonight?
You: brb, my mom is calling.
In online games
Teammate: Ready to start?
You: brb 2 mins, getting water.
At work
Manager: Can you join the call?
You: brb, saving this file first.
In each case BRB sets a clear time frame. If you think your break will take longer than five or ten minutes, it is kinder to say so.
BRB and its cousins
| Abbreviation | Meaning | Break length |
|---|---|---|
| BRB | Be right back | A few minutes |
| BBL | Be back later | Longer than a few minutes |
| BBS | Be back soon | Short to medium |
| AFK | Away from keyboard | Any, shows status |
| GTG | Got to go | You are leaving |
| TTYL | Talk to you later | Ending the chat |
Choosing the right one tells people what to expect. If you plan to leave and not return today, “gtg” or “ttyl” is clearer than BRB.
Good manners around BRB
The golden rule is simple: if you say BRB, come back. If something comes up, send a quick note like “sorry, longer than I thought, talk later?” That one line saves a lot of waiting.
BRB in different apps and settings
WhatsApp and text messages
In a private chat, BRB is the simplest way to avoid leaving someone waiting. Friends often use it with a reason: “brb, dinner is ready.”
Gaming and voice chat
In online games, BRB tells teammates that you are pausing for a short time. Many players also use “afk” for the same purpose. It is considered good manners to say it before a match starts, not in the middle of it.
Work chats and video calls
On team chat tools like Slack or Teams, a quick “brb” tells coworkers you will answer in a minute. During video calls, people often type it in the chat box when they need to step away to open the door or take a call.
Social media comments
BRB is rare in public comments, but you may see it in live streams, where viewers write it to say they will be back to watch more.
Why saying BRB is good manners
When a person goes quiet, the other side starts guessing. Did they lose signal? Did I say something wrong? A one-word note ends that guessing. It also sets a time frame, because “right” suggests a short wait. Small signals like this are a big part of why online chats feel friendly instead of confusing. If you wish people to feel respected, say when you leave, and say when you are back.
A short history of chat shorthand
BRB belongs to a family of abbreviations created when typing was slow and chat rooms were new. Alongside “lol” and “btw,” it helped people save time and add feeling to plain text. As phones took over, many of these short forms stayed because they are quick to type with thumbs. Some, like BRB, are now so common that people say them out loud, usually as a joke.
Common mistakes with BRB
- Vanishing after BRB. Leaving someone hanging for hours feels careless.
- Using it for long breaks. BBL is the better choice.
- Typing BRB in a formal email. Write “I will return shortly” instead.
- Forgetting group chats. In a group, a brief BRB helps everyone know why you stopped answering.
- Using BRB in a serious talk. If you are in an important or emotional conversation, step away with a full explanation.
How to reply when someone sends BRB
- Short: “Okay!” or “Sure.”
- Friendly: “No rush, take your time.”
- Joking: “Do not get lost!”
- When you also need a break: “Same, I will be back in a bit too.”
You do not have to reply at all. A thumbs-up reaction is enough.
Tips for using BRB well
- Say how long if you know: “brb 5 mins.”
- Come back and say “back” so the other person knows you returned.
- Set your chat status to “away” during longer breaks.
- Use BBL for lunch, meetings or errands.
- Keep your phone notifications on if you promised to return soon.
