OB

What Does OB Mean?

OB means "Open Beta" and "Oh Brother!".

Open Beta

OB is an abbreviation used in gaming and computing with the meaning "Open Beta" to refer to games or programmes that are in the final phase of development and are considered almost ready for release. OB versions of products are made available to the general public for testing in a real-world environment, in order to check for problems or glitches before commercial release.

OB contrasts with CB (Closed Beta), which refers to an earlier stage of development, in which products are only made available to invited users for testing. (Also see BETA).

Oh Brother!

In text messaging, OB is also sometimes used as an interjection, with the meaning "Oh Brother!". In this context, it is usually typed with an exclamation mark (i.e., OB!).
