The Grand Canyon refers to a girl who is extremely blown out. The relevence of this term is that, just like the real Grand Canyon, the chick's vagina is forever stretched for for a huge distance. Girls with Grand Canyon twats should be avoided, as they have seen more than their fair share of dicks and probably contain numerous STDs.

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.
