Janko Jerk 

When a person driving a car with a manual transmission jerks the steering wheel at the exact moment he/she shifts gears, in an attempt to induce wheelspin or "chirp" the tires.

Ol' Bryan took me for a ride in his mustang. It's a 4 cylinder and it won't lay rubber...so he kept trying to janko jerk it.

pity-jerk

Male masturbation to images/videos/sounds/thoughts of a female he doesn't find particularly attractive, but feels he's doing her a favor by the act.

I'd never hook up with her, but I bet she'd be happy to know I pity-jerk to her pic every now and then.
