An awesome 90's metal band from Germany who's legend is up there with Rammstein. Their songs usually involve explicit sexual stuff like rape and kidnap.
My personal favorites include:
Unsterblich
Kleid Aus Rosen
Sieben
Wenn Engel Hassen
Eisblume
Feuerkind
Stimmen
You should totally check them out, you curious little bastard.

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
