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.

Biffles would be the plural.
"You're my biffle... (may continue with other ramblings; but it's optional)"
