I remember in my highschool (all girls) PE class we had a self-defense lesson one period. For an hour we all had to hold each other in "bear hugs" and we had to mime fighting each other off. Like most things that are not in the usual schedule during highschool, it was hilarious and tons of fun.
All I remember is (if he has your hands) scrape the heel down the knee then STOMP on the foot with the heel and then HAMMERFIST TO THE GROIN. Oh man. We said "hammerfist to the groin!" for weeks. Also, I think there was a line about trying to poke his eye and then pop it out with hooked fingers? Not sure if that's a realistic suggestion, but if I were you guys, I'd stay the hell away and not try to test it.
Funny memories aside, I just want to add that highheels are really painful to be kicked with. They're pretty good awesome weapons on the foot or off. Though they are impossible to run in - which is probably the most important thing to be able to do. So, uh, never mind I guess.
Nice thread!
