Top definition
Often employed by females when talking to others (usually males) online, when they no longer wish to speak with that person but don't want to actually tell them.

They type "brb" as if to leave the chat momentarily, but never reply again, and quite often, "sign off" by blocking the person they are speaking with.
Guy 1: I was talking to this girl I met online before, she said she would brb but signed off and never returned.
Guy 2: She used the BRB trick on you
Guy 1: The what?
Guy 2: She didn't want to speak with you anymore but instead of telling you that, she wrote "brb" and blocked you.
