If you’re a parent who SRSLY gets confused trying to figure out what your kids are saying when they text or are on Twitter – rejoice, the FBI is here is to help! FBI has released a comprehensive 83-page manual for deciphering social media slang and acronyms.
The manual was published on MuckRock.com, who acquired the guide through a Freedom of Information Act request. "With the advent of Twitter and other social media venues, the use of shorthand and acronyms has exploded. The Directorate of Intelligence's Intelligence Research Support Unit (IRSU) has put together an extensive list of shorthand and acronyms used on Twitter and other social media venues such as instant messages, Facebook, and MySpace.”
It includes common shorthand like SRSLY, OMG and LMAO as well as more obscure terms like SOIDH (screenshot or it didn't happen). They defined the word troll as "a deliberately provocative message board user." Fabulous. Tax dollars at work!
