My bad

Origin

The punchy, informal phrase "My bad" is widely understood to have bounced into common usage from the basketball courts. Players needed a quick, no-fuss way to own up to a misstep—a fumbled pass, a missed shot, or a minor foul—without interrupting the fast pace of the game or sounding overly contrite. It's a swift, almost guttural admission of fault, designed for instant accountability and efficiency. From the hardwood, this casual apology dribbled its way into general American slang, becoming a ubiquitous shorthand for anyone owning up to a minor gaffe or oversight in everyday life.
