Best friends forever

"Best friends forever" ("BFF") is a phrase that describes a close friendship. Such friendships are characterized by intimacy, trust and a sense of permanence. The contacts between the close friends tend to be frequent and be based upon shared experiences such as attendance at the same school. Relationships described as such are common in high school but, rather than lasting forever, tend to deteriorate when the parties go to college. The term BFF does not convey exclusivity; people can have more than one BFF.
