Masterdate

When you take yourself out on dates; dating yourself. You already know what you're into, likes, dislikes, hobbies, etc... Dating yourself also allows you the freedom to have a great time, all the time, and never have to hear "you're not paying attention to me" or other forms of bitching and nagging. You are free to mingle with whom you please and are able to spend time enjoying life and being happy.

Could come off as self-centered, egotistic, or conceited to those who don't understand how hard it is to find someone as awesome as you are.

(A)"What are your plans for tomorrow?"

"Oh I'm going to masterdate."

"Huh?"

"I didn't stutter... and this is why I date myself.."

(B)"If I could marry myself I would, so for now I am a masterdater."

maskerbater 

A mask wearer who derives pleasure from...
1. Wearing masks in stupid places (ie: their car, shower, or bed.
2. "Enforcing" mask wearing by yelling at others to put their masks on.

Karen is such a maskerbater. She just peered over and yelled, "Hey! Stop being a murderer. Put your mask on!" - I was pooping in a stall.

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.
