"Be right back." No longer taken literally, people just say it when they are going to be gone for any amount of time, whether it be 20 seconds or 20 minutes.

Get the brbsmug. Short for brb, which some people use literally, and are gone anywhere from 3 seconds to 5 minutes. Some people, however, use it much more loosely, and will be gone for hours on end, and usually come back making a truly shitty excuse for why they were gone so long. Used mainly in IM conversations.

Get the brbmug. What you type into an IM window when you don't want to talk to that person anymore. After typing, you simply don't talk to them anymore. Thus you are spared from their company and they are not offended.
