Friend of a friend (FOAF) is a phrase used to refer to someone that one does not know well, literally, a friend of a friend.
In some social sciences, the phrase is used as a half-joking shorthand for the fact that much of the information on which people act comes from distant sources (as in "It happened to a friend of a friend of mine") and cannot be confirmed. It is probably best known from urban legend studies, where it was popularized by Jan Harold Brunvand.
The term was apparently first published by Rodney Dale in his 1978 book The Tumour in the Whale, in which he discussed the "FOAFtale".
The rise of social network services has led to increased use of this term.

Famous quotes containing the word friend:
“Our ability to fall in love requires enough comfort with our masculinity to join it with someone’s femininity and feel enhanced. . . . If our mother made us feel secure and proud in our masculinity, then we want to find that again in our wife. If we are really comfortable with our mother, we can even marry a woman who is a friend rather than an adversary, and form a true partnership.”
—Frank Pittman (20th century)
