Definition:

BFF is a term used to describe extremely close friendships, usually between young girls and teens. However, the term has grown to include adult women. In 2010, the Oxford English Dictionary added BFF as "an official noun." It originated in 1996, and is formed from the initials of "best friends forever."

While this term started with teens, it's grown in use and is now said by everyone from kids to middle aged adults.
