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.
