Masksturbation 

The act of putting a mask of your favorite superhero during masturbation to get off.
Brought upon by intense admiration and/or recreation of superhero costumes from comics.

Joey bedded the model of the month, but like Batman he still required some Masksturbation to finish off.

Comedic Masturbation 

When you are so funny by yourself that you laugh out loud without any participation by a partner.

Progresses from a small grin to a smile to a quiet giggle and then quickly reaches the climactic event of an audible belly laugh, or LOL. Following climax, tissue is often used to dry resulting wetness occuring in the ocular region.

My humor is not always understood by others and I frequently find myself involuntarily engaging in comedic masturbation.

Bureaucratic Masturbation 

noun - 1. Engaging in any activity for the sake of making one feel better about themselves, their organization, or their company without actually accomplishing anything. 2. Holding meetings to provide recommendations only to have management do what they wanted in the first place. 3. Holding special work group meetings to make the 'little people' feel ownership, when the decision has already been made by higher levels of management.

My boss has picked me to suffer through more Bureaucratic Masturbation, representing the department on a policy work group.
I spent the last 3 months researching the best candidate for the position and the Boss picked his pet employee anyway. God I hat Bureaucratic Masturbation!

Masturbation Marathon 

An exceptionally long episode of masturbation fits. These episodes are usually brought on by sexual deprivation and bordom; however, and I'm not making this up, they have been used a means of fundraising for sexual related causes such as safe sex. A masturbation marathon is a strenuous event that requires disciplined training and preparation. There are several related subcatagories such as time, ejaculation distance, and most orgasms for both male and female competitors (I'm totally serious - google it).

Hillary's return brought an end to Bill's 72 hour masturbation marathon.
