How it's used
Primarily used in the context of sports like tennis, badminton, or basketball to indicate a ball or player crossing the boundary line. It carries a sense of finality or error, often resulting in a loss of points or a stoppage in play. Beyond sports, it can metaphorically describe someone crossing a social or professional boundary, though this usage is less common than the literal one.
Examples
The ball went out of bounds, we need to serve again.
Your foot stepped out of bounds, that's a foul.

Common mistake
Do not confuse this with 越界, which is more formal and often implies crossing a moral or legal boundary rather than a physical line on a court.
