Tail-wagger 

A tail-wagger is someone that follows a crowd or a movement without truly questioning the validity or purpose for it. TailTail-waggers often copy hashtags or wear pink kitten hats. They see others in the crowd doing something, so they want to be a part of something bigger than themselves. Kind of like when you want a dog to do a trick or behave a certain way, you reward it with a pat on the back and a treat and it wags its tail, because it's excited to have the approval of the boss.

Most protestors are just tail waggers.

People that jump.
The lead singer told everybody to lift their hands over their heads and clap a rhythm. Once a few people started, then all the tail-waggers joined in.
