The FBI is just as confused about the Internet as your parents are.
MuckRock released an 83-page FBI document that attempts to define thousands of Internet acronyms. The document is called "Twitter Shorthand" and has upwards 3,000 acronyms, along with a definition. Like this: LBH is "let's be honest" or "loser back home."
The document was uploaded on MuckRock in a PDF version but it can't be read because of its low quality, so here are some of the best ones:
