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.

Manterboating

The placement of one's face, into the cleavage of a man's moobs, followed by the side-to-side shaking of the head accompanied with a motor-ing sound.

John made many trips to McDonalds on Friday; resulting in a hefty, yet delicious figure. Sarah was captivated by his rolls and decided manterboating his moobs at the pool the next day would be a hot idea.
