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 term used for someone who did something so stupid, that it's comparable to the stupidity of not knowing how to spell "genius". Mostly only usable in internet speak, since jenius and genius sound the same.
"Perhaps staying up till four a.m. wasn't the best decisions."

"U r a jenius".
