To defecate with such extreme force and vigor it renders one completely fatigued, yet very euphoric.  It usually results in the entire bowl being coated a healthy brown.  Such causes involve White Castle, grease truck food, college dining hall food.

Get the powershitmug. 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.
Girlfriend: So now that you're out of the bathroom, do you want to have sex?
Boyfriend: Nah, I just took a powershit so I'm good to go.
Girlfriend: UGHHHH. *turns on vibrator*
