Paul launches the “Yo Bitch” app, based on his character Jesse Pinkman’s favorite catch phrase, which allows users to send “colorful greetings” to friends. Paul announces the new app on Twitter:

Yo Bitch! To everyone that has ever asked me to call them a bitch, here you go. It's an App Bitch! Happy Holidays. https://t.co/CjS1rcSROe
