Acrobatic Double-Footed Nutshot
This is absolutely the most insane and brutal nutshot I've ever seen.
Apparently, this is a parkour hazing for the Tempest Free Running Academy. I don't care how badass this school is, there is no reason to do this to anybody. This crotch stomp could seriously cause some major and permanent damage.
Now, here comes the pain!
Here's a really sweet video from the Temepest Free Running Academy.
