What Does “MB” Mean?
The primary meaning of MB in texting is “my bad,” which serves as an informal apology. People use this phrase to take responsibility for small mistakes without making a big deal out of the situation.
The term “my bad” originated in basketball culture during the 1970s and 1980s. Players would say it after making an error on the court, and the phrase gradually spread into everyday language. The abbreviated version MB emerged as texting became popular, allowing people to apologize quickly using just two letters.
