The incident occurred yesterday, as the man tried to break up an argument between a group of teenage girls. At one point - one of the girls - who weight less than 90 pounds pushed the 51 year old giant.
The grown man - who is 6 foot 3 and weight more than 250 pounds punched the girl with all his strength. The man is now claiming "self defense."
The video has gone viral for another reason - the attacking 51 year old man is White and the 12 year old victim is Black.
