masturjacking 

Masturbation in an extreme sense.

He was perched up on the sink like a monkey, bent over and masturjacking like there was no tomorrow.

Masturjoking 

When one tells a joke only to please themselves. The masturjoker often intends to please a crowd with their joke, but ultimately fails, and is the only one laughing.

Adam: "Man Alex thinks he is really funny, masturjoking over there. No one gets his humor."

Jess: "Well you always tell him to try out his jokes on kids first!"

Alex *laughing* "Oh man I'm so funny!!"

Masturoaching 

Not just the act of masturbating your cock, BUT the act of masturbating your cock while within seconds of achieving orgasm, a cockroach swoops right over your cock, causing you to jump and unload all over the place.

Example of Masturoaching:

You: "Eek...!" -moans/heavy panting-

Roommate: "WHAT!?!1one1?!"

-Awkward Silence-

masturpacing 

The act of pacing the room while masturbating, often characterized by bumping into furniture the closer you get to climax. Usually done late at night by insomniacs and results in a high amount of random bruising.

"Every night at like 3am we can hear his floorboards squeaking as he walks around. He must be masturpacing."
