"Insufficient data."
Insufficient data?!? Can't you just make an educated guess?

F.B.I. stands for floppy ball index. The index ranges from 1-5, 1 being really tight, and 5 being the floppiest it can be.

Fucking Big Indian: A large man or woman of indiginous roots. Commonly sighted at bingo halls and beer holes, this species can be quite dangerous when approached.

To avoid harm, look directly at the F.B.I., and slowly back away. It has been noted that throwing coins will distract them.
You walk into a bar or a bingo, and what's the first thing you see? That's right, it's an F.B.I. staring you down like you were a word they couldn't understand.

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.
