I've become one of those crazy people who has gotten sucked into Breaking Bad and can't stop annoying everyone around themselves by talking to about the show. Addictions are more fun when you share them with other people, right? If only it were more socially acceptable to say bitch, I'd be saying "Bitch! Bitches! Yeah, bitch!" like Jesse Pinkman all day long.
To understand "bitch" the way it's used in the show, you have to get to know the character Jesse Pinkman, who is really just a cute kid who wants someone to love him, see his potential, and help him grow up like the parents he never had. Then you know "Bitches!" is Jesse's way of protecting himself from the mean, cruel bad guys in the world.
