Masterbaton 

The muscle between your elbow and inside of your elbow that grows more and more every time you masterbate.

John - Woah man! Your arm is huge!
Freddy - Thanks man! I've been working on my masterbaton.

Masterbathon 

a masterbathon is a day that you stay home from school "sick" so you can beat off so many times that you are dry and chaffed and can't walk so the next day you have to stay home and do it all over again

Maskerbator 

An individual devoid of reason and logic that tries to shame rational people into wearing a useless paper mask,especially in outdoor environments.

“Hey,let’s go give that jogger a hard time because he’s not wearing a mask outside”
“Go to Hell Karen....you’ve become nothing but a useless Maskerbator“.

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.
