Noun: The object at the end of a shift lever in a manual transmission car, usually made from vinyl, leather, or metal, depending on either the manufacturer's or owner's taste.
That shift knob is pure bling.
My new shift knob is lighter and helps me shift gears better.

Must be performed in a vehicle with a manual transmission. With the proliferation of automatics, shift-knobbing is a dying art and talent.

Shift-knobbing is when you are driving and your passenger partner (M or F) provides you with sloppy, wet road head all while they simultaneously operate the shift knob for you changing the gears with precision accuracy. Thus freeing both your hands to control the car or use one hand to drive and the other to return a little sexual gratification to your partner in one of their reachable erogenous zones.
Rachel and I hit the back roads to head to the beach. The drive when by smoothly as she was shift-knobbing with pinpoint accuracy. The bumpy back road route caused a few throat plunges and gasps for air.
