The way of describing a person who listens to techno and is a mad good shuffler. To describe more than one of these people the word becomes 'Shufftekz' because the inclusion of the letter 'z' makes everything so much cooler. The original word was created by a girl called Lily Colin for the original and still best Shufftek of all time; Josh Potter
That guy is such a Shufftek!
Check out that group of Shufftekz!
