Be Right Back (BRB) is a common phrase used in online chats, gaming, or text messaging to inform the other person that the user is temporarily leaving but intends to return soon. BRB is often used when someone steps away from their device for a short period, such as to take a break or handle an immediate task. It?s a courteous way to let others know the conversation is paused, but not over. Even in the age of real-time communication, BRB remains popular among Gen Z as a quick, informal way to communicate brief absences.
