This term is commonly misunderstood as "Be Right Back" where one individual in an online conversation has to leave for a certain amount of time during a good conversation.

This is actually wrong though, it has a very firm meaning of "Bringing Ryne Beer" and often times is heard daily.
Person #1: "So whats up?"
Person #2: "Hold on, BRB"
Person #1: "Isn't that his 4th beer today?"
Person #2: "Yes - hold on, you know he gets cranky if I don't bring it right away"

'Net chat slang, or "netiquette" for "be right back." The term does not, however, actually mean, "be right back." It is a segue euphemism for "get lost," "f*ck off," "I'm not interested in you," "never in a million years, you troll," etc. Used mainly in dating or sexually oriented chat.
Sure, I would love to meet up sometime. brb

brb is an acronym for Be Right Back.
People use it in online games and chatrooms mainly, teenagers use it when they really gotta jerk off, while younger kids use it when they must eat or they parents yell at them.
