Power Shift 

Power shifting is a technique used by drag racers in order to achieve faster acceleration and lower elapsed times during a race. To power shift a manual transmission vehicle, after inital launch and upon reaching the engine's power curve peak, you must keep the accelerator fully depressed, apply the clutch, upshift, and release the clutch. This must be done quickly and smoothly in order not to damage the engine by over revving during the shift. Power shifting is used only for upshifting, never for downshifting.

If you power shift while drag racing, you'll achieve a shorter quarter mile elapsed time.

Power Shift 

On a manual transmission car, power shifting is when you shift gears without using the clutch - waiting for just the right RPM, and then slamming the stick from one gear to the next.

Power shifting is advantageous if done correctly because you change gears without spending any time clutched in - during which time your car normally cannot accelerate.

"Dude that guy can power shift really good, if you race him, you'll get owned."

"... Yeah but I heard he's on this third tranny now."

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*
