B.F.F

B- Big
F- Fat
F- Fucker

I used this since before best friends forever ever started. Original DOS, kermit word.

If I saw a guy at school that was huge, we would say B.F.F on our KERMIT conversation. If you do not know what kermit is, then look it up and you will see how old I am talking about. LOL
