What does BFF mean?

Say itbee-ef-EF/ˌbiː.ɛfˈɛf/noun

Stands for
  1. BBest
  2. FFriend
  3. FForever

A very close friend, usually your best friend.

BFF is short for best friend forever. It means your closest friend, the person you text first with good news or bad news. Merriam-Webster defines it simply as “a very close friend” [1]. You will see it in texts, birthday posts, and photo captions, and adults often use it as a joke.

Say it letter by letter: bee-ef-EF. It is informal but never rude. It is often linked with girls and young women, and one dictionary says a BFF is “typically a girl’s” best friend [2]. Anyone can use it, though, in both American and British English.

Where it came from

  1. 1978Merriam-Webster dates the first known use of BFF to 1978 [1]. It comes from the first letters of “best friends forever.” Dictionaries do not say who first used it.
  2. 2010The Oxford American dictionary adds BFF, defined as “a girl’s best friend.” Other new words that year include “unfriend” and “hashtag.” [3]
  3. TodayBFF is in major dictionaries, and people use it for old friends, helpful coworkers, and even their slow cookers.

Can BFF be a joke?

Yes, and adults use it this way a lot. Dictionary.com notes that BFF is sometimes used jokingly [2]. Besides your real best friend, BFF can mean:

  • Someone who just helped you. The person who lent you a phone charger is your “new BFF” for the day.
  • A close ally. News writers sometimes call a group’s allies its BFFs, as in “the oil lobby and its BFFs in Congress” [2], often with a little sarcasm.
  • A useful thing. A slow cooker or a warm blanket can be “your BFF.”

How do you know which one it is? Look at who or what is being called a BFF. A friend of fifteen years is a real BFF. Someone you met this morning, or a kitchen machine, is a joke.
