A 9-sided polygon. The latin root orginates from the word "nona" which means ninth of the ninth. 9-9 or 1/9. Or just ninth. Read the book Virtual Mode by Piers Anthony for more relative relations on the modes and Julia set.
The nonagon has 20 parallel demensions. One is the Burgess set. I don't know any others. They are intersecting, but still parallel. Just fuck me, my brain hurts.

Nonagon Infinity 

A music album released by the Australian psychedelic rock band King Gizzard & The Lizard Wizard in 2016.

The name "Nonagon Infinity" refers to the number of tracks on the album (9) and also to the album being a so-called Concept Album where every song flows seamlessly into the next, the same holding true for the closing track which flows seamlessly into the opening track which allows the album to be, theoretically, looped indefinitely.

The website nonagoninfinity.com features an infinitely looping stream of the album. At the time of writing it has already looped 36,753 times.

Monkey Circle / Monkey Nonagon 

Monkey Circle (also known as Monkey Nonagon depending on how many people are in the group) is a commonly used expression when defining the country Netherlands. Monkey Nonagon backwards is Netherlands, they use this quite often in their chants. If you are ever able to survive the Monkey Circle initiation(which less than 1% do) you will be promoted to a "Monkey". A "Monkey" is the lowest rank you can have in the Monkey Circle / Monkey Nonagon. This role is not important, and many are sacrificed daily in their rituals. If you are lucky enough to survive the first couple of rituals as a "Monkey" you are then promoted to the "Netherlands" role. This role basically does all of the management in the Monkey Circle / Monkey Nonagon. If one "Netherlands" dies, then all the current "Monkeys" must be sacrificed. After becoming "Netherlands" you have to cut both of your arms off and eat your penis before you can advance to the "Belligerent Fag" role. This role is the highest role you can be in the Monkey Circle / Monkey Nonagon. Only .000001% of people make it to this role. This role congregates ALL of the Monkey Circle / Monkey Nonagon meetups. If it were not for this role, the Monkey Circle / Monkey Nonagon would NOT exist.
Yo. you wanna join the Monkey Circle / Monkey Nonagon?

I don't know man, they're pretty serious about their rituals, I had a friend go there, he fuckin' died dude.

Damn das' crazy but ion remember askin' doe
