Coincidental Race Theory 

a theory that racism doesn’t exist and it’s all just a big coincidence that minoritized peoples have ended up where they are in Western societies, particularly the US; often espoused by people who are defensively insistent not only that they are not racist, but that there is no way they could possibly BE racist.

Forget what they learning in school, this prejudice moron must have learned more about Coincidental Race Theory from his own ignorant parents.

coincidencialism 

the belief that there is no higher truth or purpose and that everything is just the result of a highly unlikely chain of coincidence after coincidence, and thus there is no way of knowing what will happen, nor is there any reason to why it happens.

coincidencialism is believing that everything that happens are just coincidences.

coincimental

A coincidence that is far to outlandish to be real this being coincimental.
"coinci" part of the word coming from coincidence meaning:a striking occurrence of two or more events at one time apparently by mere chance.
And the "mental" part of the word coming from the slang and informal usage: slightly daft; out of one's mind; crazy.
Basically a beefing up of the word coincidence.

You and a friend seperatly go shopping for an outfit for a party. Upon arriving at the party both your outfits are identical. "Thats fucking coincimental mate".

Coincident 

The dent ALREADY ON the exact spot of the car you near nearly drove into.

"I was on my way down to the Yentagon when some joker cuts me off. And wouldn't you know it... total coincident! Right on the fender I was about to slam into!"

As they don't say:

"Better a coincident than a $500 deductible."

Coincidentally ironic 

When some is a coincidence but it is also ironic

When you work at a knife factor but you forget to take one for yourself to use for a party. This would be deemed coincidentally ironic.

cowinceidental

Refers to what someone unfamiliar with having his teeth worked on thinks dat da face-scrunching pain dat he feels during said agonizing operation is.

Before modern-day anesthesia, da fact dat having a tooth pulled/drilled hurt so much was hardly cowinceidental.
