This starts off just like any other fight between fans at a sporting event, with two guys puffing up their chests and talking some shit while the rest of the crowd waits for something to happen. It escalates quickly when a bystander decides to get things moving with a beer to the head, and then it really escalates when the two combatants go flying down the stairs together.

I think it's safe to say that both guys ended up losing this fight.
