"freddy who? i'm just trying to impress a girl. the other boys are being all tough. they're going to call me a pussy, and then she'll think i'm beta. that other guy has broken three cars already."
in the long run, the key to stopping this is largely economic. in the short run, it's probably not going to be fixed with parenting or policing. rather, young women ought to pick up a tactic from the ancient greek comedy lysistrata.
so long as the cause and effect relationship is made clear, that'd get these young boys under control. in the mean time? the plain truth is that tactics that are successful are going to continue.
