masterbatorium 

A confined space used for masterbation. A masterbatorium will sometimes have pictures of naked bodies hanging on the walls for visual stimulation. Those little rooms in the porn store that you stick quarters in, those are masterbatoriums. A masterbatorium will generally smell of lotion or crusted semen. You get a feeling of filth when you walk into a masterbatorium.

The guy who lived below me had his room completely wallpapered with centerfolds of Playboy Playmates, this was obviosly a masterbatorium.

McMasterbate 

When you have McMaster history homework and you procrastinate by masterbating, wasting precious time needed to do work.

I had a ton of homework yesterday but I decided not to do it and McMasterbate instead.

Hey Evan last night I McMastebated all night!

masterbator 

A person who is a 3rd degree black belt in the art of masturbation. A masterbator doesn't need physical stimulation all he needs is meditation to be able to complete his task.

Dude 1: Look that guy is sitting there by himself with the look of extreme pleasure in his face. He's also making weird noises too.

Dude 2: He's a masterbator he's able to masturbate with his mind.

Yak: That's right I am a 3rd degree blackbelt masterbator. No need for women or porn and no getting cockblocked. And look no hands! hahaha.
