When I was in high school, I saw two cha-cha girls go from throwing words to fighting in the blink of an eye. It took 6 security people (3 for each girl) to separate them. There were press-on nails, clumps of hair, and bits of clothing on the floor when they were taken away.
@GayDeceiver When I taught high school, I had no problem stepping in to break up fights between boys who were much larger than me. Girls fighting? Oh hell no. Call the popo!
