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!
