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

brb doesn't just mean "be right back". That is a lie. When a woman tells you brb over chat (JUST brb, nothing else) that means she doesn't want to talk to you anymore. If she says something like "brb for 5 minutes my mom is having a heart attack" then MAYBE, just MAYBE, you can try to believe she genuinely has to get off the chat. Watch out for this guys, if a girl texts you this, you're probably wasting your time. The best solution to brb is to LET IT GO.
Me: So, I really had fun last night, we should totally do it again, don't you think? How does tomorrow night sound to you? ;)
Girl: (Another day with this douche bag? fuck that!!) brb
Me: Um...okay. :) (Damnit, I fucked it up again! This is the third this month!)
