Short for "family prices". The term is used by hippies
and music festival attendees to assure potential customers (custies
) that the products being sold (shirts, jewelry, drugs, etc.) are at fair, almost family-like, prices.
However, majority of the hippies using this term sell their products over-priced and often times unreasonably high. It is a deceptive term to those unfamiliar with the Festival scene, making individuals feel as though they're getting a good deal when in reality they're getting ripped-off.
The term is very ironic, being that it is supposed to signify a person's family-like actions when selling a product; the truth of the matter is that the seller is tricking the customer and portraying very non-family-like behavior.
