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 words friend of and/or friend:
“A friend of mine spoke of books that are dedicated like this: “To my wife, by whose helpful criticism ...” and so on. He said the dedication should really read: “To my wife. If it had not been for her continual criticism and persistent nagging doubt as to my ability, this book would have appeared in Harper’s instead of The Hardware Age.””
—Brenda Ueland (1891–1985)
“If your friend has displeased you, you shall not sit down to consider it, for he has already lost all memory of the passage, and has doubled his power to serve you, and, ere you can rise up again, will burden you with blessings.”
—Ralph Waldo Emerson (1803–1882)
