I don't think women feel that they can whoop a man's ass, unless he is tiny, but they think that men will not hit them.
Some believe that a man is supposed to take whatever she gives him whether it be verbal abuse, in your face confrontation, being spat on, hit on with an object, slapped, etc.
But, as you see in the video, not every man is going to put up with certain shyt from a woman.
Bottom line,
Big man was wrong because despite her mouth, she posed no threat to his safety...
Sometimes, a man gotta walk away especially if he is temperamental and is prone to use physical force..
