MB Meaning in Chat

The phrase “My Bad” first emerged in American street slang in the late 1970s. The first recorded usage appeared in the book “Back-In-Your-Face Guide to Pick-Up Basketball” in 1986. However, it was the 1995 movie “Clueless” that made the phrase famous.

As digital communication evolved, users shortened frequently used phrases into abbreviations. This trend led to the creation of “MB” as a simple, two-letter representation of “My Bad.” Today, MB is widely used across texting apps, gaming platforms, and social media.
