A brb fail is what happens when you say you'll 'be right back' and then either take an absurdly long time to return or get pulled into something that makes the original conversation irrelevant. Classic brb fail moves include: disappearing for three hours after saying brb five minutes, coming back when the conversation has fully moved on, or returning to a situation that has entirely resolved itself without you. It's a well-worn internet experience — harmless and extremely relatable, typically met with jokes rather than genuine frustration.
Said brb, ended up watching four episodes of a show and came back six hours later — classic brb fail.
