An extremely nasty individual, so awful they can only be described in one word that is a combination of a witch, a bitch and a snatch.

One day and friend and I were talking about someone we didn't really like and all 3 of the these words (witch, bitch and snatch) just came slurring out of our mouth at the same time. So we coded the word wiznatch and have used it ever since.
As I was walking in the mall, I spotted that wiznatch who was talking behind my back the other day.

Get the wiznatch mug.
A person who steals the wii remote from a little kid when they are playing Super Mario Bros. Usually a Wiznatcher will be older than the victims playing the game. Often the Wiznatcher will be very obsessed with the game and only caring about winning. One word of advise when u ever come face to face with a Wiznatcher is never play Super Mario Bros. with him!
Waaaa!" The baby cried. "Mommy! That Wiznatcher stole my Wii!
