an acronym that stands for Federal Bureau of Investigations. Also an acronym for Face Book Investigations one of the F.B.I.'s internet crimes divisions.
I called the F.B.I. on somebody who is stalking me on facebook and the operator referred me to the Face Book Investigations unit.

Face Book Idiot: A person whom you've never met, befriends you on Facebook, and after reading your comments and looking at your profile...thinks they know you, and begins to judge you as such. This person begins to comments on conversations you are having with "real friends" you know as if they know you. Seriously? This is the epitome of an F.B.I.
You know that guy that trolls me once in awhile? Well, he just commented on a conversation I was having with my brother and said something so unreasonable as if he knows me. Really? Let's hope this guy never ends up on a jury. Time to block him, he's an F.B.I.
