BRB (https://saferloop.com/brb/) was designed to be used for text-based communication, but today, it is also spoken almost by everyone, particularly during informal or game-related voice chats. Verbal communication has adopted the usage of BRB when addressing friends, or in the case of an online group, when an individual requires a brief pause. Even better in high-speed dialogues, it is faster than the reason you are leaving and it is easy to use. Nonetheless, it is still informal and thus it is not advisable to use it during professional voice calls or during serious dialogues where clearer and more polite wording is required.
