Seems like gang bullying is a good description
I don't think Town was trying to get people to pound you into submission.
I think Town was trying to cause you distress, to hurt you.
No different than a bully twisting your arm just for the fun of it, or a thoughtless little kid pulling the wings off flies.
He's a sadist who enjoys tormenting others.
Town was acting as a bully plain and simple. The ones he called out to and complied with his request were acting as his lieutenants. Anyone who can't see that the repeated "red marking" of someone is cruel is emotionally bankrupt. And the one who calls out for it is responsible.
Bullying ranges from simple one-on-one bullying to more complex bullying in which the bully may have one or more "lieutenants" who may seem to be willing to assist the primary bully in his or her bullying activities.
