Just one hour into the New Year, a massive fight erupts in downtown Sarasota, and it doesn't seem coincidental it's right next to a brewery. The video begins with a skinny guy in a fake Versace shirt taking a fighting stance. The skinny dude tries looking tough ... dancing around as if he's ready to trade blows.

Well, he gets more than he bargains for, because another guy punches him, knocking him back against a car. Then, another guy from the group lends a hand and sucker punches him.

And then ... a guy hovers over the dude and literally uses his face as a punching bag, striking him more than a dozen times.

Another fight then breaks out nearby, and eventually cops come to break it all up.

The Sarasota Police Watch Commander tells TMZ, cops responded to 2 separate fights. In each fight, one person went to the hospital, although no one was seriously injured.
