"Throw this Identity Disc at friends and watch them 'derez' in pain!"

This has to be a first; a toy company suggesting you throw their product at your friends to give them a painful death.

Its a Frisbee - We throw them at each other all the time.

Although it is a rather nice Frisbee ;-)

Not to "watch them 'derez' in pain". Though I must admit that would be amazing to watch the first few times.
