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.

Something a girl says when she will aparently "be right back" (like 5-10 min), but really means she's ditching her friends for her boyfriend (1 hour-Forever!). At first you might believe... But after a while you will learn that "BRB" means she's not coming back.
If your good friend starts saying this beware... Your friend time with her is limited!
Girl: "Brb" guys!

Friends: "Okay see you tomorrow"

Girl: "No really, I'm coming back!" (leaves)

Friends: "Let's bet on it... 20 says she's not"

2 Hours later...

Friend: "Pay up!"
