3.

The term derives from students that attend a public school solely because they reside in close proximity to the school (i.e., "residential students"), as opposed to attending the school for a specific higher-level program (i.e., "magnet students"). Use of the term, however, can also be applied outside of the school context, and to people exhibiting these characteristics in the broader world.
