When a man uses his hand to move his penis in the H-Pattern of a manual or "
Stick" shifter like he is shifting gears on a
car. Often, the man will also use his girlfriend's boobs or vagaina as a steering wheel or
clutch pedal.
Person 1: Man, I did the dick
shift really hard last
night, and her boobs were the perfect steering wheel shape
Person 2: Did you
hit the perfect downshift?
Person 1: Yup, and I finished soon after. It was awesome! Will do again, 10/10!
