"Nah yay lee" :3 or "Nah yeh lee" I'll answer to both. It's basically the same thing, just a slight difference in inflection on the ye. And I'll give yours a go!
"Nic uh dee mys"?
"Za moe rahn"?
It is quite nice. :] Does it have any specific meanings? Nayeli is Native American; a large part of me is NA, that's why I felt better with a name to feel connected to my roots. It means "love" or "I love you", depending. And Niji is the japanese word for rainbow. Arkoiris is a play off "arco iris" which is spanish for rainbow. So, essentially, "I love rainbows" ;P
