She can be very self conscious and rude, but can care for others in a kind and beautiful way . She is an amazing friend but can go cold if you don't do as she says. She is all around boys and does try to take the center of attention a lot , but if you meet a Nyah try to keep her close , but don't get on her bad side.

Sometimes the word nyah is even extended to furthur draw out the intensity of the word. Often used while twisting the curled end of the moustache.

Nyah is a sweet, gorgeous girl with loads of compassion towards others. She’s generous, fun, and overall an amazing soul. If you know a Nyah, make sure to keep her around, because she’ll make your life the best it’s possibly able to be.
Gosh, Nyah is such an amazing person.
