You’ve probably seen it — that one message in the middle of a chat that simply says “mb.”
The first time I saw it, I stared at my screen, trying to guess what it meant. Was it a typo? A hidden code? Or some new Gen-Z slang that I had somehow missed? 😅
If you’ve ever felt the same confusion, don’t worry — you’re definitely not alone.
Quick Answer: “MB” means “my bad.” It’s a casual, friendly, and slightly apologetic way of owning a mistake or acknowledging a small mix-up. Think of it as the quicker, text-friendly version of saying “Oops, that’s on me.”
🧠What Does MB Mean in Text?
“MB” is short for “my bad,” a slang phrase people use to apologize casually for something minor — like forgetting to reply, misunderstanding a message, or making a tiny mistake.
It’s not a serious or formal apology; it’s more like saying “my mistake” in a light, relaxed way.
Example:
A: “You sent the wrong file 😅”
B: “Ahh mb! Sending the right one now.”
In short: MB = My Bad = A casual apology.
