a way of doing an alcohol shot, usually whiskey, in which a full shot glass is slid down a bar or table and the person doing the shot grabs the glass just as it's about to fall off the table and shoots it in one seamless motion. Must be done with real glass since the danger of the glass falling and breaking is part of the appeal.

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
