WATCH: Fan learns touching UFC star Matt Brown during his walkout is a truly awful idea

Understandably, Matt Brown didn't take too kindly to a fan pulling his hood during his walkout at UFC 198.

Top UFC welterweight Matt Brown knew he was really up against it in his bout against Demian Maia in Brazil. Grappling master Maia seems to have the ability to beat just about anyone in the 170 lb division right now and Brown admitted that the reason why he opted for the fight was because h knew the momentous challenge that it presented. https://twitter.com/SportsJOEdotie/status/731098939466911745 It's fair to say then that "The Immortal" was pretty pumped up for this fight, which makes what one fan's decision to try to wind him up while he made his way to the Octagon on Saturday, all the more idiotic. As Brown made his way to the cage before the fight, a fan reached out from the crowd and pulled his hood. Without hesitation, Brown turned to the fan, shoved him away and gave him a terrifying glare that we can only assume caused him to soil his pants on the spot. The fight itself didn't go so well for the American as Maia once again put his BJJ black belt to good use, smothered his opponent for two rounds before sinking in the rear-naked choke at 4:31 of the third. The win was the Brazilian's fifth on the bounce and 17th overall in the UFC.
