How do you spell "Dysfunctional"?

People always say they came from a dysfunctional family. But what is that really?

Diss - People are always dissing each other
Funk - Usually an "out of sorts" mood at home
Shun - Force the non-compliant person out of the "in" group
Ill - Everyone is sick emotionally and/or physically

Put it all together and you have diss-funk-shun-ill...
