Question: Ask The Nuwaupians, Why Do So Many of You Use the Term Rayay(a) as Part of Your Online Pseudonyms?
Answer: Because of their lack of study outside of York's theology, and the cult's ideology; is why they're clueless on this language reality.

This won't take long, it's very simple and to the point: someone has Nuwaupians using a term labeled to be Egyptian (Rayaya) when it's NOT found in ancient Kemet (Egypt) but is in part taken directly from ancient Sumerian language 𒅴 𒆠 𒂗 𒄀 𒊏 (eme-ki-en-gi-ra).  

With the elaborate names/titles for the Nuwaupian male and female such as; Seneb San Atum Rayay, Nusur Rayay Atum, TaffaNatat MatatAmsu Rayay, Harkuf Haru Rayay, Nat-tat Ranantat Satat AatunRayay, Huni Sanan Atum Rayay, Khufu Atum Rayay, or Tefnut Amun Rayay, nice sounding cultural names, however, "Rayay/Rayaya" is not Egyptian (to be sure York never used such a term) thus this term labeled, or implied as Egyptian, is only found within the circle of the Latter-Day Nuwaupians.

The Nuwaupian cult: using their conlang; which is a constructed language whose phonology, grammar, and vocabulary, was manufactured, not a natural development from an ancient source, but intentionally devised, artificially constructed/invented using multiple other language terms to imply being original; in a nut shell (artificial).  In using their conlang, they have the word  "Afaf Rayay Kaaah-u" to mean "African" with no textaul sources for verification.  However, with the vast imagery of Kemet being the Nuwaupian cult's foundation, these "Afaf Rayay Kaaah-u" are Egyptians.  We know from the Latter-Day Nuwaupian literature that they (via the leader York) are the Egiptians (the spelling Egipt is a Spanish spelling Egipto).

"In each religion they see some human being, coming from above to Earth with more power than earthlings, who can transform himself.  Yet, when WE EGIPTIANS said our Khaman-u 'Ogdoads' were symbolic of frogs and snakes of the deep...the fact is they really believe the very same things that WE EGIPTIANS knew.. The Egiptians who are African ["Afaf Rayay Kaaah-u"] were in Africa first..."
-Malachi York: Natural Ether Energy pg. 7-8

It's clear from the Nuwaupian teachings, that the Munwap-u (Nuwaupians) are (Afaf Rayay Kaaah-u) (Africans) therefore the pseudonym Rayay for African, is their self identification.  Unfortunately it is NOT an Egyptian/Egipto term. 

So where exactly does this word come from?  It's taken in-part from the Sumerian term for a grandfather; are the Nuwaupians all African grand fathers, men as well as women?

𒀀 𒀀 𒀀 /a/a/a/ trium of the /a/ vowel written out as ayaya.  So you have the word for a grand father in Sumerian ayaya, if you were to add the /r/ and remove one of the /a/ vowels; you'll get the pseudonym "Rayay". 

 The word for father in Sumerian is 𒀀𒀀 a-a = father, (reduplicated) offspring.  

𒀀 𒆪a-ugu4[KU] the father who begot someone (semen+procreate) (Halloran).

𒀊 𒁀 ab-ba, father, an official, elder [male] in Sumerian is an Akkadian loan word "abu", plural abbū.  This Akkadian word gave birth to the Semitic words,

Proto-Semitic: *'ab

Arabic: 'ab أب

Syriac: 'abā ܐܰܒ݂ܳܐ

Hebrew:' אָב

Ugaritic: ab

Ge'ez: 'ab

It's nothing too complicated, just a typical case of poor Nuwaupian research, lazy scholarship, and a flawed methodology.
