The Shooting Brock Press is what we called that back in the day. If someone fell off their skateboard and landed on their ass or any kind of botch like that, I'd tell them they did a Shooting Brock Press.
It's too bad he didn't actually hit the move because it would have put an exclamation point on WM19, which I think was otherwise the best WM ever (yeah, better than 17, by a shade).
It's funny because going into WM19 there were two things I wanted to see: Brock finally do an SSP, and Booker T do a Harlem Hangover (his somersaulting elbow drop off the top that he never did anymore). While there was zero indication either would happen, I actually got BOTH of those things. It's like I willed them into happening.
I wonder if the SSP would have been Brock's finisher going forward if he'd hit it here. Or at least a "special finisher", like when Undertaker can't finish someone with the Last Ride or the Chokeslam so he'd go all the way to the Tombstone.
