Nicholson's "Bad Ass" is a beautifully crafted piece of character. He cusses. He fights. He drinks. He's loud. No one else speaks Robert Towne's words better than Nicholson. In this film he overwhelms at every turn. In the bar scene, he shows brute anger and a desire for dominance. The scenes with a young Nancy Allen are delightfully witty because of Nicholson's schoolboy antics of getting a woman into bed.
It is the scenes with Randy Quaid (also wonderful) where Nicholson shines brightest. "Bad Ass" represents a paternal figure lacking in Meadows' life. He makes him a man by demanding he send back a hamburger if it's not cooked the way he likes it. He demands Meadows to stop crying and be a man. He demands Meadows to stand up for himself and fight when someone pushes his buttons. He demands Meadows to want to have sex, like other men his age. Nicholson's father figure image here is played off perfectly as Meadows sort of imitates things "Bad Ass" does. If Bad Ass has a beer, Meadows has a beer. If Bad Ass wants a woman, Meadows wants a woman. There's a secret trust between the two. It's unspoken, but it's there. That trust is broken in the end when Meadows tries to escape. It wasn't all a lie, Meadows just felt that it was time to stop learning and start moving.
