The heartless and extremely one dimensional character in a movie that is so mean and evil or dickish
, that you can't help but hate him. He is also often characterized as the killer or abuser of beautiful and defenseless wives & girlfriends and innocent children, or the dick
boyfriend of the leading lady that you cannot for the life of you, figure out why she's with him.
He either dies near the end of the movie in a very sadistic and creative way at the hands of the the good guy, or he is humiliated in front of his peers and those he's wronged. In either case he is such an asshole
that his form of death or humiliation has given the writers an easy out to give the audience something to cheer and feel good about.

It was revealed that Zack, in Wedding Crashers, was the Puppy Killer, when he bragged about his sexual conquests behind his girlfriend Claire's back and how he was using her just to advance his political career.
