Ninwa 

A girl that smiles a lot. She tends to be from exotic Persian or Assyrian descend. Confident and is always singing. She is funny even though she thinks she is not. She is especially good at searching out and finding the truth. She tends to operate on a rather different wavelength, and many of her friends may not really know her very well. She can be wild too in the good sense of the word. Ninwa is a synonym for fun and happiness.

1. Lets go out and have some ninwa
2. I'm having a bad day today, I need some ninwa time
3. Dude.. I had so much fun yesterday, I totally ninwaded out!

Nintaijutsu 

Nintaijutsu is a martial arts system made up by an Youtube celebrity named Greg park, in 2007. Greg Park is a resident of Los Angeles with Korean ancestry. Utilizing his background in TaeKwonDo training he invented his own martial art which he named Nintaijutsu, which is based around his own theory that Japanese Ninja were originally from Korea. Although historians, history books, and all evidence does not support his theory, he has continued to gain over 75,000 followers to his Korean stealth martial art.

14 year old kid with a Youtube account: Hey dad I'm practicing this new stealth martial art over the internet! It's called Nintaijutsu and it's what ancient Korean Ninja practiced before they immigrated to Japan and taught the Japanese the art of the Ninja!

Japanese historian dad: *puts kid through wall for failing as his son*
