FFI 

A fingerboard forum named FingerFlipInc.
A place where fingerboarders go to to discuss fingerboard issues.
Most of the older people on the Forum are constantly out to get the younger fingerboarders for no reason whatsoever they go on about how all the new people T1pE L1eK dIs nD bump everything.

The forum is supposed to be fun but all the trolls like Alex moores,jesse wormald, simon cartledge and Kyle Friend to name a few are always making everyone unable to enjoy the forum.

Bill: Wow these new tech deck products look Sick!!!!11one

Simon: No tech deck are just a Fu*k off of decent products they don't care about the scene. Now get off of FFI.

fatal familial insomnia (ffi) 

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

person: hey whats fatal familial insomnia (ffi) ?
yes, it means fatal familial insomnia and that means an illness that kills you overtime from weight loss, dementia, and sleep deprivation basically.

Instant messaging lingo.

During an online conversation if one finds something funny, but not funny enough to laugh, one might have a very slight outburst of breath from the nose. This is a 'ffins.' AKA a reversed sniff.

A word for those who are sick of people that say lol, lmao, and rofl every single thing.

A subtle way of telling someone online that you found what they said funny, but you're not laughing.
