The term was coined by Lindsay Lohan, after declaring her chauffeur as her "Best fucking friend." Being high, Lohan's pronunciation wasn't very clear, and the words 'fucking friend' were misheard by two twelve-years-old white girls discussing Miley Cyrus' new album, "Sex, Drugs, and Incest with my Dad," as 'friend forever'. The term has also been abbreviated as Biffle, which is an abbreviation of the abbreviation 'BFF', to abbreviate it's usage more than it's already abbreviated. The word Biffle also gives everyone mental images of a baby elephant, for some reason.
