In modern internet and gaming slang, the acronym OOB most commonly stands for "Out Of Bounds." This term originated in traditional sports to describe areas outside the legal playing field, but it is widely used in video gaming and speedrunning communities to denote glitches, exploits, or developer oversights that allow a player's character to move outside the intended, rendered map boundaries. Less commonly in enterprise technology, it can stand for "Out-of-Box," referring to pre-configured hardware or software features.
