Face Book Intermission - a brief respite from the philosophical, intellectual, cultural, family-oriented, self-centered, political, food-tripping, ego-tripping, arrogant, creative, opinionated, plagiaristic, bla, bla, bla posts, comments, and shares in Face Book. Often, but not always, the F.B.I. is about a term derived or influenced by U.D. (Urban Dictionary). Sometimes the term is posted first in F.B.I. before it appears in U.D.
I'm tired of all these pictures and comments from my ex-girlfriends and ex-boyfriends... I'm now ready for F.B.I.

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.
