A person who thinks they're "perfect" and deserve extra points in classes for repeating what has just been said. These people tend to have big arrogant egos and do not know they are insane. Most of the time their names are Nick and Adolf, but especially Nick; always the male form, never feminine such as Niki or Adolfa. The reasons behind acquiring this disease is most-likely the act of being a stage manager. Avoid insane people especially the ones named Nick and Adolf for they tend to spread lies about how "awesome" they are.
"Don't hate. You're just jealous you didn't get extra points for being awesome like me."

"What's there not to like about me? Oh, wait. I'm perfect. I (almost) forgot."

"I'm the stage manager. do what I say"
= Insane, Touched, Foolish etc.
