Jul 26 Word of the Day
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
I got a call from X the other night. She had an extra ticket to a concert she bought for a friend, but they couldn’t make it so she called me to ask if I wanted to go because I am her Second String Friend.

A step sis likes to masturbate, the step sis is so clumsy she gets stuck atleast twice a week, no matter where it is, a step bro will always use this opportunity to have sex with her and jack off, you will often hear this sentence follow, "WHAT ARE YOU DOING STEP BRO ". If a step bro catches her masturbating, the step sis can now tell their parents that her step bro watched her masturbating, so she will tell the step bro to have sex with her and she won't tell her parents.
