A best friendfor life. A girl or guy, whom one is best friends with. Someone who you can trust and whom you love a lot, but as a friend. And only a friend.
This is my biffle Chelsea, we do everything together and have a lot in common. I love my biffle, she is my best friend for life. I would never want to lose my biffle,she is an amazing friend.
An idiotic word which shows how the acronym 'BFFL' would be written if it became a proper term, god forbid. It means 'best friends for life', although in most cases this is generally a lie as you often lose contact with friends, especially if they were made when you were young.
