Get the Nief mug.
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.
