The motif recurring in folklore (legends, jokes) of an overly large (even grotesquely vast) vagina--in which objects become lost, into which entire persons tumble, etc. Clearly a projection of masculine fears of sexual inadequacy, the image epitomizes the concept of the voracious and insatiable sexual appetite attributed to some (or all) women. The term was coined (in English, at least) by the folklorist Elissa R. Henken; see Henken and Mariamne Whatley, Did You Hear about the Girl Who--?: Contemporary Legends, Folklore, and Human Sexuality (NY: New York UP, 2000) 121.

Noun: a friend who is usually only called upon by a friend when a more primary/prominent friend is unavailable.

Taken from the term “second string” in an athletic competition situation. In football, if the star quarterback gets injured during a play, the second string is called off the bench to replace him/her. A “Second String Friend” is essentially benched until needed, if ever.

Synonyms: Plan B, Second Choice, Secondary Friend, Benched Until Needed
