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

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.
