Replying to I had a "Shitty" bail, literally.

So the other day we were riding and having a great day on this fun mid-sized park, everything was sweet.  Until I got the stupid idea to try an overflip, figured it'd be the opposite to doing unders.  Rolled up to this jump that was about a 20footer, with waaaay too much speed, and tried to throw an over.  Ended up completely bailing out, starting to spin, then ended up upside down and basically got  slammed right onto my back on the flat, about 40ft rather than 20.

  I landed so hard that I SHIT MY PANTS.  I'm not kidding.  At first I thought I was dead, then I thought it was my tail bone sticking out of my skin, then I realised it was a turd hanging out of my butt. Nice.  Some of the worst pain I've ever felt and I still can't feel my legs, but yeah has this ever happened to anybody? Why?  And yeah I pulled up the bottom of my pants and it rolled out. Haha
