A phrase used to accuse someone of staring at you, often used by Drill Instructors at Marine boot-camp. The point being that if someone does't have a valid reason to stare at you (like you owing them money) then they should stop doing it.

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
