Overachieving-ass dweebs (like Hermione) that are in all your biology and chemistry classes. They let everyone around them known that they are pre-med either directly or indirectly through their obnoxious behaviors (including, but not limited to: asking questions about how the material is relevant to the medical field, whether or not the professor has finished writing them a recommendation letter, and boasting about their shadowing experiences). An important thing to note is that not all pre-med hermione's are actually smart, but pretend to be.

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
