People have been knocked out with a Superman Punch. Travis Browne Vs Stefan Struve, James Irvin vs Houston Alexander just two examples in MMA.
Yeah, but stomping you face first into the concrete would ruin your life for real.
You're losing your teeth, breaking your nose, etc. . . If somebody "curb stomped" you for real.
Yeah, a "Superman punch" works in context of a MMA fight, but a curb stomp is just some brutal terrible real life shyt that like I said, I'm surprised is even allowed by WWE.
Anybody who's seen "American History X", which I'm assuming is where he got the move/name from should know that shyt is awful.
