"i r back" - "I are back", the less grammatically correct way to say "I am back."

The follow-up to brb, "be right back".

Used in IM conversations- or real ones, if your friends are that blind and you're too lazy to speak in complete sentences.
A: Guess what?
B: brb

B: irb, what'd you want to tell me?
A: ...crap, I forgot.
