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.
