Girls are not given their due out of boys' natural inclination to behave honorably (an inclination very few girls naturally possess). When a girl abuses a boy's mercy long enough, she should be told to be prepared for the consequences.
At the end of this video, the boy asks if the girl is okay. It's likely he asked this because he feared the consequences of having physically hurt her. A fear that didn't even cross her mind.
Girls should be reminded swiftly that this behavior will not be tolerated in our culture. It should be made painfully clear to them that it is savage.
How sad is it that we now have to educate girls about the natural respect they need to have for boys? That if left uneducated about it, they are literally stupid enough to believe they won't lose a physical altercation.
Girls, don't ever hit a boy.
Women, don't ever hit a man.
Update: Another stupid woman
