Marshawn Lynch went beast mode Friday night trying to break up a fight incited by a Seattle Seahawks hater.

Marshawn and his crew were leaving a San Francisco bar when a drunk guy taunted the running back, repeatedly calling him a "Seattle Sea Chicken."

Someone in Marshawn's crew snapped and a melee erupted. You see Marshawn in a white cap trying to pull one of his friends away from the guy. An eyewitness tells us Marshawn got in a few punches before walking away.

The fight adds to the lore that there really is such a thing as Chicken of the Sea.
