When you submit a post to a thread and nobody responds, sign up with a couple of extra accounts. Make each of those accounts bump your post to make it more popular. This happens a lot on Digg, 4Chan, and so on.

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.
