n. The process of masturbating under any time pressure. Also a sport when played competitively.
I had a meeting in 5 minutes, but I just really needed to rub one off. I was speedsturbating my ass off!

Alright, everyone, you know the rules to Speedsturbation. Money in the pot in the center of the hallway. I say go, first person to enter their dorm room and successfully finish, clean up, and come back out gets it all... GO!
