My old high school had a powderpuff football game during the week of homecoming. I believe it was a night or two before the actual game. It was typically Juniors vs. Seniors or Freshmen/Sophomores vs. Juniors/Seniors. It was always two hand touch or flag football. It was never tackle. They never wore pads or helmets. They would typically wear old jerseys that were not being used anymore. It was more for fun really, but there were times where a hit was made that had a message behind it. I never saw any fights happen at those games. You could tell though that some were competitive with it, and those that were, took it seriously and didn't mind putting another girl onto the grass.
