Poo-knuckle Hole-jacker 

A long piece of soft cloth (about 3ft or 100cm) with four or five knots tied at even intervals along it. .... is placed between the legs and the ends held in each hand, one in front and one behind, as if being straddled (usually with your clothes still on).
To use: The rear hand is lowered as the front hand is lifted and vice versa. Repeat this action; causing the Pooknuckle Holejacker to move between your legs, while the knots are bumping you.

This may or may not be a good thing.

Therefore, this word may be used to describe a bumpy ride, a rough person or a really horny person.

Person 1: Hey - have you seen my Poo-knuckle Hole-jacker
Person 2: Yeah, you left it on the bathroom floor.
Person 1: Oh, thanks .. .. .. .. You didn't use it did you?
Person 2: No way! I have my own Pooknuckle Holejacker.

or:
OMG that road was so bumpy! I wont be needing my Pooknuckle Holejacker tonight!

or:
That guy is a roughbastard, what a Pooknuckle Holejacker!

or:
My boyfriend is so horny! He's like a Pooknuckle Holejacker on steriods. Yay!

poo knuckle 

The slightly less pleasurable, but still delightful act of receiving a handjob while taking a shit. The predecessor to the blumpkin.

Stephens girlfriend was too stingy to give him a full blown blumpkin, so she elected to give him a poo knuckle. He was meagerly satisfied.
