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

Boi is a very rare species of frog found only in the north coastal area or at the Gulf stream. They eat bees, flies, and sometimes birds. They are carnivores and, instead of using their legs, they ride a one cycle bike for transportation. They are light green with small, black eyes. They can also speak some of the human language!
