something that literally traumatized the haikyuu fandom forever. its a rare disorder that affects the part of your brain that controls the sleeping cycle. patients usually die from it within year or two. something used in a bokuaka fanfiction, (bokuto x akaashi) and it killed akaashi's lover forever and now we're all emotionally numb
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(mostly non fingerboard related). 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 that makes them superior to most. But there is still a lot of cool people on ffi that aren't cocky or complete dumbasses and fingerboard just to fingerboard.
