There seems to be a disconnect between what you think bullying is and how it actually manifests. Between adults, the behavior would be classified as unprovoked assault & battery. Someone punching you in the back of your head while you weren't looking, without a word being said between either of you, because the other person's peer group dared them to is not a failure of the victim's conflict resolution skills.
To be clear, as a victim, I was subject to unprovoled physical battery like this more time than I can count between the start of middle school and my second year of high school. As a bully, in my senior year, I never engaged in any kind of physical violence, just name calling and verbally provoking someone prone to emotional outbursts.
