NicsterV

What that "ZephPlays" guy said. Seriously, what he said is true. NicsterV is a fucking clickbaiter that all the 4-10 year olds watch.

Random 8 year old imposter: I am real nic
Me: No you're not. Besides, even if you were, I fucking hate NicsterV anyways, so shut the fuck up.

Noncester

A noncester is not just your average, small time nonce.

A noncester is prolific in his fiddlings of multiple victims and can only be described as a monster nonce for his many deplorable acts of paedophilia. A Noncester.

Bailey, mate, clock that guy by the main school gates. It's Keith the noncester spying the hopscotch again.

Nickster

A putt in golf that is absolutely going into the center of the hole when, at the very last second, is mysteriously taken over by an unknown gravitational force, dives for the edge of the hole and violently lips out. This usually occurs after all of your playing partners have conceded the fact that you hit a great putt while secretly willing you to miss.

Good par Bill, OH NO, a nickster! How did that not go in?

Niester

An unusual possibility of someone whom is a niece and a sister at the same time; capable of occuring when a woman has a child with a father and another with his son, or when a man produces children with a mother and a daughter, the niester being the result of the one person and the younger generation (having the child with the son or daughter) as related to the other child.

Family reunion this weekend! I can't wait to see Colleen, whom is my niester. What's a niester you may be asking yourself? Well, my Dad had a kid with my sister, which makes her my sister and my niece at the same time. Yeah, I know, we're a bunch of rednecks.
