Cage man. Much more primitive and aggressive than your typical cave man. Where a cave man has the freedom to roam in and out of his cave at his leisure, the cage man spends its life confined to a small cage. Very rarely will a cage man escape this torment. But when it does, it will unleash the type of hell a cave man could only dream of.

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
