An expression used in AIM conversations. Though technically meaning "be right back", it is more commonly used as an excuse to leave a conversation with a person you don't want to talk to anymore.

An Acronym for "be right back," according to Netiquette should be used for an absence less than or equal to ten minutes, if the allotted is above that then bbiab should be used instead if you're not logging off, otherwise use bbl

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!"
