A word used to mask a swear word being said. The main purpose of the word is so no one knows that you are swearing.
Nyi is used when you hit your finger with a hammer in front children. If you hate your boss and you with to curse him. If you are very pissed off with some one. Simply say "Nyi" on it's own.
