I’m going to assume that grappling — a sport I am, admittedly, not familiar with at all — has its fair share of dirty moves. Is farting one of them? How about farts that are so rotten that the guy taps out because he vomits from it? That’s what happened at the NAGA Grappling Championship in Las Vegas over the weekend, when one poor fella got the tail end of one guy’s lunch, before immediately unloading his own.
