PUTTING ALL DOUBT TO REST ... THERE'S NO SLAPPING IN BRAZILIAN JIU JITSU.

As if you needed me to tell you this.  Still, if you watch the video below, you'll see not everyone got that memo.

So, yeah.  This video here, from what we can see  and put together from the comments, shows 2 blue belts competing in a BJJ tournament.  From stand up, the guy in the white gi seemingly accidentally (although maybe recklessly) knees his opponent in the face.  What follows is a cranky full-on retaliatory bitchslap from the guy who received the knee and then a lot of pacing and sulking. 

The video has about 23,000 views now - that's über insane viral by BJJ standards.  It illustrates how much we all enjoy a quality slap in the face, even in the BJJ tourney setting.

Here's my take on this, in brief - slapping an opponent is just bad form.  If I had a dollar for every time I've been kneed or otherwise smashed in the face while training (by elbows, heads, heels, etc.), I'd have at least $1,000 by now.  It's a rough sport, and stuff like this happens ALL THE TIME.  Recklessness should be avoided and everyone should make every attempt to avoid accidentally striking opponents/teammates, but it's still going to happen.  Retaliate like this (and videotape it) and ne'er-do-well (and super cool) grappling websites will put it on the internet and mock you. 

Grapple on.
