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."

masturspacing 

The act of spending all of one's free time on MySpace looking at the profiles of complete strangers.

(Usually leads to several random, unknown people being added as friends, while using most of the bandwidth on your internet connection.)

Joe is hogging all the bandwidth because he's been in his room masturspacing to random skanks all night.
