What does B. F. in B. F. Sword for?

A lot of people say "Best Friend", but that doesn't make much sense.

I personally think it is a reference to the "BFG" from Doom, which means "Bio-fragmentation Grenade", but its nickname is "Big Fucking Gun", so "BF Sword" would be "Big Fucking Sword"; which it is. That makes the most sense to me.

Long-standing tradition from the BFG-9000 in Doom.

Big fucking sword, it's a reference to doom as stated by der lindwurm

ya

Likely it's like B.F.G. which is a children's book.

It actually means "Bubble Foam Sword" :^)

Could stand for almost anything.

Boy friend.

Boy Friend Sword

Banana friend =)

Honestly, it's just an internal code from when the game was being designed. "Big Fucking Sword". BF Sword.

As I understand it from a ranked game last night it means "Best Friend Sword"

And it is a nice sword to have.
