#114 Whoosh?

I'm not really sure how to explain what it is that I tried today. We were at my mother and father-in-law's house and found this toy thing. It's red, football shaped, it's on strings with handles and I can't find it on the internet. I can say I've never done this before and it somehow turned into a battle to smash that thing as hard as you could into the other guy's handles so it would hurt. Not mention the intense tricep workout I got as result, I'm already feeling the hurt.
