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.

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.

A sexual act performed by a male/female couple and a third which can be male or female. The couple prepare for sex in the doggie styleposition. The third party then cups the male's balls in the palm of their hand and extends their middle finger out and along and against the bottom of the male's cock. The male then proceeds to enter the vagina filling her with both his cock and finger of their partner at the same time. Thus giving her a satisfying knob and knuckle.
