Is the "Sports Wave" That Crowds Perform at Sports Arenas

Is the "sports wave" that crowds perform at sports arenas really a "wave" as physicists define the term?

A) Yes, because energy does move through the crowd from one point to another, and this is what we mean by a "wave" in physics.
B) Yes, because a disturbance does move from one point to another without a corresponding transfer of matter, and this is what we mean by a "wave" in physics.
C) No, because there is no real physical connection between the different parts of the medium.
D) No, because spectators have free will-- that is, they are not really forced to stand up and participate.
E) No, for both the reasons stated in answers C and D.
