What Does “MB” Mean in Slang?
In modern slang, the most popular meaning of MB is “My Bad.”
It’s a quick and polite way to admit a small mistake or take responsibility for something. Instead of saying “I’m sorry” or “That was my fault,” people just write “MB.”
Example:
- “Oops, MB for not replying sooner 😅”
- “MB I thought it was tomorrow, not today!”
The tone is casual, friendly, and not overly serious. It’s used between friends, co-workers, or anyone in a light conversation where a full apology would feel too formal.
