Usage

What else does bb mean? In text messages and online, bb can be short for baby, especially as it's used as a term of endearment for significant others or friends. In this sense, it can sometimes be pronounced as [bey-bee]. Bb can also be short for quite a few other things, including basketball, bye-bye, the pellets of a BB gun, and some NSFW applications.
