FFI is short for Finger Flip Inc, a fingerboard forum. Even though it is a fingerboard forum people go there to get into fights about every little thing. Also a place were everyone likes to suck up to the FlatFace team and get on there good side just because they are better than most(even though some of the team sucks) of us they are superior. But there is still a lot of cool people on ffi that aren't cocky or complete dumbasses and fingerboard just to fingerboard.
