BFFL is a term used to describe an unbreakable union between friends. Typically used between two drunken girls at a Denny's after a night of drinking and shenanigans.

A BFFL is not spoken letter by letter in abbreviated form example- B.F.F.L. pronouncing the letters individually makes you a dumb ass and gives it less meaning.

A true BFFL is pronounced as a word in whole, when spoken properly it should sound like (BIFFEL) but always be spelled BFFL

BFFL can also be used as a noun example- "We are BFFLING"
Heater is Belinda's BFFL

Belinda is Heather's BFFL

When Heather and Belinda go out drinking and get faded they are BFFLING to the max.
