You're in the middle of a heated group chat or maybe a quick back-and-forth with your boss on Slack. Suddenly, the doorbell rings. Or your cat decides to knock over a glass of water. You don't have time to type a paragraph explaining the feline-induced chaos. You just type three letters: brb.
It’s reflexive.
Most people know that brb stands for "be right back." It’s the digital equivalent of holding up a finger to say, "Give me a second." But even though it feels like a permanent fixture of our phones, the phrase has a weirdly specific history that explains why we use it differently than almost any other acronym.

What does brb mean in a text message and where did it come from?
Before we had iPhones or even T9 texting, we had IRC (Internet Relay Chat) and ICQ. This was the early 90s. If you were online, you were likely sitting at a bulky beige desktop computer plugged into a wall. You couldn't take the conversation with you to the kitchen. If you had to pee, you were literally leaving the "chat room."
The term brb was born out of necessity. It signaled a temporary physical absence from the terminal.
In those early days, being "online" was a binary state. You were either there or you weren't. Today, we are always "on." We carry our chats in our pockets. This has shifted the meaning of what it means to "be right back." Now, it doesn’t necessarily mean you’re walking away from a computer; it means you’re stepping away from the attention of the conversation.
Honestly, it's a courtesy. It’s a way of saying, "I’m not ghosting you, I just have to do something else for five minutes."
The Nuance of Modern Texting
It's funny how a three-letter acronym can have different "vibes" depending on who sends it. If your best friend sends "brb," it usually means they’re grabbing a snack or someone walked into their room. If you’re in a gaming session—think League of Legends or Call of Duty—typing "brb" in the team chat is a high-stakes warning. It means "I am about to be stationary and useless, please don't let me get killed."
In a professional setting, like Microsoft Teams or Slack, brb has become a tool for boundary setting. It’s a polite way to tell a coworker you’re heading into a meeting or taking a lunch break without having to provide a full itinerary of your day.
Why we haven't replaced it yet
You’d think with emojis and voice notes, we’d have found a more "modern" way to say this. But we haven't. According to digital linguist Gretchen McCulloch, author of Because Internet, acronyms like brb and lol have survived because they function as "social signals" rather than just abbreviations. They facilitate the flow of a conversation.
They provide "phatic communication." That's the fancy linguistic term for talk that doesn't necessarily convey big information but performs a social task. Saying "hello" is phatic. Saying brb is too. It maintains the social bond while you’re temporarily unavailable.
Compare it to gtg (gotta go) or cya (see you). Those feel final. They end the session. BRB is a promise. It’s an "I'll be back," which keeps the door open.
The "BRB" vs. "BBL" Distinction
Back in the AOL Instant Messenger (AIM) days, there was a strict hierarchy of away-messages.
- brb: Back in 5-10 minutes.
- bbl: Be back later (usually an hour or more).
- afk: Away from keyboard (the gamer's choice).
Today, bbl is mostly dead. No one uses it. We’ve consolidated everything into brb. Why? Because our sense of time has compressed. If you're going to be gone for three hours, you usually just stop replying. You don't need a specific acronym for it because the expectation of an immediate reply drops off after a certain window anyway.
The Etiquette of the "Be Right Back"
There are unwritten rules here. If you send a brb and then don't come back for four hours, you’ve technically lied. You’ve committed a minor social foul.
In romantic texting, "brb" can sometimes be a "soft exit." It’s the "I’m going to go to sleep now but I don't want to say goodbye" move. Or worse, the "I don't know how to end this conversation so I'll just say I'm stepping away" move. It’s the ultimate low-confrontation escape hatch.

Then there’s the capitalization.
- brb (lowercase): Casual, quick, no big deal.
- BRB (uppercase): This feels urgent. Like, "I need to go right now because the oven is on fire."
- brb... (with ellipses): This is ominous. It suggests you're annoyed or the thing taking you away is something you're dreading.
Context is everything.
Surprising Fact: The Longevity of the Acronym
It’s rare for tech slang to last 30 years. Words like "pwned" or "rofl" have mostly faded into the cringe-inducing background of the early 2000s. But brb persists because it is functionally perfect. It’s easy to type on a thumb-keyboard. It’s phonetically simple. It fills a gap in human interaction that didn't exist before instant messaging: the need to announce a temporary departure from a non-physical space.
Is it ever inappropriate?
Probably don't use it in a formal email. If you’re emailing a client, "I will get back to you shortly" is the move. brb is too twitchy for email. Email is asynchronous; it’s expected that you won't reply for a bit.
Using it in a text message, though? That’s almost always fine. Even with your parents. Interestingly, "brb" is one of the few pieces of "internet speak" that older generations have fully adopted. My 70-year-old aunt uses it. She might not know what "no cap" means, but she knows exactly what brb means in a text message. It’s universal now.
Taking Action: How to use it better
If you want to be a better digital communicator, don't just use the acronym—use it with intent.
- Pair it with a reason if it's going to be long. "brb, jumping in the shower" is better than a vague "brb" followed by 30 minutes of silence.
- Use it to save a conversation. If you see a friend is going through something but you have to walk into a grocery store, a quick "brb" lets them know you're still there for them, just momentarily distracted.
- Check your "away" status. On platforms like Discord or Slack, if you’re going to be brb, actually change your status. It prevents people from getting frustrated when you don't reply to their "urgent" pings.
Ultimately, the goal of texting is to bridge the gap between being together and being apart. Three letters might seem small, but they do a lot of heavy lifting in keeping our digital relationships healthy.

Next Steps for Better Texting:
Start noticing the "silence" in your chats. If you find yourself leaving people on read for 15-20 minutes during an active conversation, try dropping a brb. You’ll notice the "vibe" of your chats stays much more positive when people aren't wondering where you went. Also, take a look at your most used emojis; if you aren't using the "running man" or the "clock" emoji alongside your texts, you're missing out on some great visual shorthand that complements the classic brb.
