note: This takes some planning, a pair of nylon gym shorts, and willing ..or unaware partner to work. When a guy has been doing an athletic activity and has swamp-sack (foul smelling scrotum) he will close one leg opening tight and then he gets his significant other to blow air up his shorts only to have the air circulate and exit back out the same leg hole into her/his face.

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
