Orgitorium 

A place where wild orgies are held. It stems from Roman roots, because they had random group sex all the time. All the fucking time. Because of this, some dumbshit Roman said hey lets make a building to have orgies in! It then became the Roman standard for emperors to try to construct the grandest Orgitoriums to hold the most hot italian bitches. They constantly competed with each other, thus filling rome with many such Orgitoriums. Many of these still survive today, but be careful where you step ;)

Sextus: Hey Octavius lets go to the Orgitorium to celebrate!
Octavius: Rofl YAY!

When a group of people gather together before an event in an arena, theatre, stage, or other ground of assembly and attempt to make small talk which usually turns to strange, disturbing, and controversial topics.

Tram: Why are those girls behind us talking about smearing peanut butter on ceiling fans?
James: What else do you expect in an odditorium?

Da community theater where weird 'n' wacky entertainment is performed.

Jeff Dunham has some really goofy content in his puppet-show performances, so one would likely need to go to an odditorium to see him, since ordinary "classy 'n' cultured" venues probably wouldn't book his performances.
