nief 

A ridiculous word with no meaning what-so-ever.
It was fabricated by some weird child that is convinced he is black.
Sorry sweetie, your white. Embrace it. <3

Ryan: NIEF!!

Andrew: Nief13!!!

Kim: Don't be stupid.

Andrew: Sorry. I like trying to be black sometimes.

Ryan: Me too.

Kim: Embrace the light, Children.

Ben: I wish I was a child of the night!! NIEF NIEF NIEF NIEF13!!!

And that is why Ben doesn't have any real friends.

nieffer 

A baddie. The hottest girl you would ever meet. Has a great sense of humor and is super fun to be around. She is someone who will always be honest with you, no matter how bad the truth may be. She has great style and can rock any outfit.

“Why is everybody staring?”

“That’s because Nieffer just walked in”

“Damn she’s gorgeous”
