White Phosphorus, given the name Willy Peter in Vietnam also used in the book "Fallen Angels"(about the Vietnam war). Usually used as a name rather than an object. Willy Peter was usually used in artillery shells to clear sections of forests rife with Congs. White Phosphorus also eats through skin which made it incredibly painful for the enemy and the shells also acted as fragmentation explosives.

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
