Unception

Derived from the movie Inception.

Similar to how inception is placing an idea into someone's head while asleep. Unception is completely removing an idea from someone's head while asleep.

Billy woke up and couldn't remember how to speak English, he must have been Unception-ed

Tom didn't want to take his math test so he when into his teacher's dream and took away his ability to do math in a fine display of Unception.

Leonardo DiCaprio's job would have been a lot easier if he had decided to do Unception instead of inception.
