B.F.U.I.K.Y is an acronym for

Best
Friend
Untill
I
Kill

You.

It's supposed to be used jokingly (please dont kill people..it's not nice)
It's explained in its self.. not much else I can say.
You've been my b.f.u.i.k.y for almost 5 years, and although you can piss me off occasionally, your the coolest person I've ever met and I love you bro, you're not LIKE my sister, you ARE my sister..

get it straight.

we're best friends.............till I kill you.
