You’re scrolling through WhatsApp, Instagram DMs, or a group chat with friends, and suddenly someone replies with just two letters: “mb”. No emojis.
No explanation. Just mb. You pause for a second and think, What does that even mean? Did they make a typo? Is it slang? Or is it something serious?
This kind of confusion is very common in today’s fast-moving digital world. Texting and online chatting have changed the way we communicate.
What Does MB Mean in Text?
The most common mb meaning in text is:
“My bad.”
When someone types mb, they are usually apologizing for a small mistake. It’s a casual, informal way to say:
- “Sorry”
- “That was my mistake”
- “I messed up”
It’s often used when the error is not serious, like replying late, misunderstanding a message, or making a small slip in conversation.
For example:
- “Oops, mb, I sent the wrong link.”
- “Mb, I didn’t see your message earlier.”
In most texting situations, mb = my bad. This is the meaning you’ll see most often in chats, DMs, and comments.
