What do call a bail in skateboard?

I mean if you fail doing some tricks on the skateboard,theres a term for failed tricks.
So what is it?

haha well theres "bail" . which means when you bail on a trick...so your either just about to attemp it or in mid attemp and then dont do it.
another word is stacking...but these are for when your about to get the trick and you dont.
theres not really any slang worrds for a failed trick...you just didnt get it
