Runnelling 

To put an animal, mainly rodents such as gerbils, rats, mice, etc. into one's anus, preferably with a safety cord, for sexual pleasure.

(Please note; This is most likely illegal and very painful. Don't do it. Please, for the love of all that is holy. Just think of the poor gerbils...on second thought, don't. Ever.)

John: Man, Jake put a snake up his ass, last night.
Jim: You mean he's runnelling?

Russelling 

Behavior that simulates actual work, while, in reality, not performing work at all

Programming emails in the morning to be sent out at various times during the day while spending the rest of the day at the bar drinking Margaritas.

What are you doing today Joe?
I am Russelling!

Jack Russelling 

To grab your girlfriends anus hair between your teeth and shake your head vigorously. Just like a Jack Russell wrestling with a piece of rope.

Similiar to motorboating but rectal and hairy.

I was Jack Russelling a girl I met in town all night and now my neck hurts.

Quantum Tunnelling 

An inter-spacial sex manoeuvre whereby a moist, warm hole is penetrated with enough irrepressible force from a cherry rocket to break through a seemingly impenetrable barrier.

Susan: “Thanks for the Quantum Tunnelling Kenneth, now I have to stitch it back together!”
