An advanced form of handjob when you lie on your back with your penis erect and a girl grips and moves it like the pattern of a stickshift (manual transmission in car). The gear ratios are determined based on your pain tolerance.

For example, she should shift from 1st to 2nd once you start to scream in pain, like high revs on an engine.
Brad: Yo dude last night was fucking NUTS I had a girl give me a Daytona 6-Speed!
Chad: Damn bro that's crazy did you make it to 6th? I usually start crying at 4th gear.
Brad: Yeah I did but she thought my asshole was the clutch...
