Forget passwords: the FBI wants to crack your internet slang. Thanks to a FOI (freedom of information) request published over at Muckrock, we now know that the Bureau is TCOB (taking care of business) when monitoring the nation's social media use. Bypassing UrbanDictionary or the odd Wikipedia definition, the FBI compiled its own 83-page list of over 2,800 acronyms that range from the well-known, like LMAO, TMI, YOLO and SMH, to the outright ridiculous, including EOTWAWKI (end of the world as we know it) and IITYWTMWYBMAD (if I tell you what this means will you buy me a drink?) The agency says the list will help agents "keep up with your children and/or grandchildren," and also invites them to add their own. Perhaps that's why AMOG (alpha male of group) and DTP (disturbing the peace) have made it in, but we secretly hope it was an Engadget reader who added KIRF (keeping it real fake).
