Hoya is a word you can replace "hi" with. It's just a lot more aesthetically pleasing to the tongue, and you can say it fast, slow, loud , quiet, (etc.) It's a lot less boring then hi, and it NEVER gets boring! If you want it to be even less boring, add "honey honey ya" to the end of hoya. However if you do this, you have to sing the phrase now.
"Hoya honey honey ya! My day way fabulous!"
