Or laughing your *** off at the sheer stupidity of butt scooting on the street..... by anyone even a world class grappler.

I don't care who you are if you are butt scooting on the street thinking you are going to leg lock someone you have a world of hurt coming your way and it probably will be sooner rather than later.
Let's not get absurd Hanzou! Let's keep the video as the joke it was meant to be!
One of the worst things you can do in any martial endeavor is put people on to high of a pedestal. A world class grappler is a world class grappler usually in the sport that they work out in. Options within that sport do not relate well always to the street. Some times they do and some times they don't!
I am sure every person you just mentioned would laugh at the idea of them butt scooting on the street.
I thought we were past this!
