i heard everyone say this was a hook. but i clearly see an uppercut, can someone educate me what makes this a hook and not an uppercut

its a lead uppercut but since he was advancing forward the body mechanics behind the punch are half hook half uppercut, but the angle of the punch is an uppercut, it was inaccurately said as a hook but its pretty much an uppercut, i wish i could go into detail but unless you train striking its hard to describe with words

its called a HOOKERCUT, u fuking clown

just a lead left uppercut. nothing more
