^Popular/Unpopular: It usually only important in small groups of
  people, cliques in middle school (groups of 3 or more) and among
  closed communities whose admission requirements are up to the
  whim of the members and subject to judgement by the group.
  Attempting to "be popular" in a particular closed community can
  be a tricky manuver, because the rest of the group is always
  asking, "Is she coming in? or is he on his way out?".

  Few cliques survive middle/high school and most people abandon
  the model, although among isolated communities it can still be
  consider important.
