It’s called a bob and weave and truly it’s the most beginner of boxing defense. The guys hands where not going to his pockets so then the threat is maybe he swings on you which by the point he moved his foot in your direction you should be prepared is going to happen. Fighting is about discipline. The footage would suggest those two were probably being drunk and obnoxious, hell one of them ran off at the beginning which you don’t do if your boy is going to throw fists. This guy is a hothead and doesn’t have the discipline to be a boxer. Punching two dudes in the glass jaw can be life altering and completely unjustified for being a drunken boob.
