Showing off stupid stunts rarely ends well. People have died doing what you did.

So sorry that happened to you, really, and that they were so low about it...no empathy. But you probably shouldn't "attempt" a stunt like that just because others are doing so.

If you know how to do backflips and this just went horribly wrong, FYL. If you don't know how to backflip and you did it because others were doing it, then it's sort of both FYL and YDI. I'm not sure.

Glad you seem to be basically ok, since you're able to post this. While it may seem fun, stunts like that are rarely a good idea, and it's probably good things got shut down before something worse happened. A guy from my graduating class in high school became a quadriplegic after pulling a stunt like that at a party. He had been a promising athlete.

Not surprised they were pissed, OP. There were ankles to sprain, pelvises to shatter, and necks to snap, but YOU cracked your head before the main events could kick off!

If they're more worried about their stupid party than your head, you're better off with new friends anyway.

Oh my god, I just want to say are you OK now??

Stupid is as stupid does. There's always one.

Unless you're amazing at backflipping into a pool, you really should only practice it from a diving board. There's a much lower chance of hitting your head on that and the damage wouldn't be as bad.

aleast they didn't leave you or push you on the side so just they can continue
