When you take a shit, and while still on the can, jerk off. It's best to wait until the shit has left your body before you begin yankin'. This maneuver is a real time-saver. It works best if you can manage to bring a laptop or other source of porn in to the bathroom with you.

Boyfriend: Nah, I just took a powershit so I'm good to go.
