The short term for 'Be Right Back' which usually means that people have told their friends via text or internet based social services that they have gone somewhere for a brief period of time which usually stand for the time of up to half an hour unless they've said that it would be longer. Although in some cases, the term of BRB can also mean that they have gone for more than 6 hours without any hint of what they are doing, which usually suggests that they are having a hard time trying to masturbate properly.
Dave - Hi Josh do you want to go online in a sec?

Dave - OK :)

Dave - Where the hell have you been? To the other side of the planet and back?
Josh - No I went to watch about 20 movies and never mentioned it to you because I couldn't be asked telling you.
Dave - Ok :(

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.

Stands for "be right back". Used in IMing. Some people actually do come right back after saying brb. Most people don't come back after saying brb. Brb is used for an excuse (some of the time) so that the other will stop talking to them, but they won't have to go offline. Usually responded to by "kk" which means "kay, kool"
