F.B.I 

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.
