A versatile word, most often used as a greeting.

It can express enthusism, surprise, dismay, and delight, but whatever the usage, is best shouted with vivacity and extreme obnoxiousness.
Usage 1- A Greeting:
Sighting an old friend on the crowded subway platform, Chris got his attention by crowing "NYIII!"

Usages 2 and 3- Surprise, dismay:
Clicking a link he was told would lead to an anticipated movie trailer, Chris was confronted with the horrific visage of Goatse. "NYIII!" he shouted, frantically hammering on the Back button.
