If this video teaches us anything, it's that there is absolutely no shame in admitting defeat. It's a pity Jiu-jitsu fighter Dimitri Salem didn't take that on board before going up against Ethan Crelinsten at the ADCC West Coast trials recently.
Grappling star Ethan Crelinsten had Salem trapped in his second match of the tournament, and was expecting Salem to submit. But, instead of tapping the mat to admit defeat and break the hold, Salem refused to quit and instead suffered a brutal snap to his arm. I couldn't watch this without wincing. I guess the moral of the story is to TAP OUT!
I feel really fucking light-headed after watching that.
