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.
An organization of federal workers, or agents, designed to secure the US against security risks that disrupt the government somehow "clearing the picture" for other departments/agencies/forces or sending in their own forces for exigent purposes. They also have a nationwide web of phone/webtaps, informants, spies and undercover guys ("plants"). Founded in 1908 with the purpose of fighting crime more effectively nationwide, they eventually lasted through trying times such as the Prohibition, WW1/WW2 and 9/11 and continue their work today.
An agent: a suit with an signed ID. Usu. seen with a 9mm handguns, black Sedan and a red tie. *Some believe they are actually aliens.* ::GASP::
