"Friend by friend" sounds really strange as a name, don't you think? Ever thought why it is called like that? Hint: It's not because of ESL.

Did you know that Friend By Friend (FBF) could be named like this because of Yukis annoying tick to brand things with "SOS"?
O is 4 steps away from S in the alphabet. So he just went step by step until he found initials that he could forcibly bend into something that sounds like it makes sense, no matter if it sounds strange. In case you missed it, B is also 4 steps away from F, seemingly making it the ideal choice for his "code".
But that's just a theory. A gaaayyyyyy theory.
