Mentally Insane is used to describe unstable or emotionally fucked human beings. The habitat of the Average Mentally Insane Human is Either a Padded room, Dark Ally, Or in the Antidepressant isle at your Local Wal-Mart. These people should be treated as you should treat a younger sibling, Using them as servers is acceptable but locking them in a closet while forcing them to watch Broke Back Mountain is torture. They should be handled with caution as they are fucked in the head and should be treated as so. Don't get too attached, They could become a Serial Killer and then You'll have to write them once a month in the High security Prison. But remember, Being Mentally Insane doesnt make a person less of a Person. It just makes us normal people Better.

A new level of understanding, so sane that anyone who is sane judges you as insane when you're actually just smarter than them in ways they can't imagine.
If an outsane person tries to tell sane people that the universe is infinite thus so is probability so they're aleady dead so fuck it, the sane person will give a quizzical look of perplexment and walk off like a douche-bag this, may also occur when you try to explain that life is pointless

A completely unreasonable person who constantly reacts with anger or any other extreme emotion when they do not get their way often over simple things "normal" individuals take in stride, but not insane enough to be placed in a home (due to frequency of occurences) but still causes enough misery and grief for themselves and others around them.

A bunch of hardcore ghetto clowns who are insane, and they rap about violence and Santa Claus. Seriously who the fuck gave these losers a contract? They can't rap, their songs have too many curses in them obviously to enhance their "baditude", their lyrics are written by retarded 5 year old monkeys, and they have a cult following of Juggalosers.
