F.B.I.

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.
