clan nutsys

something crazy, difficult, or confusing.

A phrase nearly identical to the term 'nuts' but totally cooler for those who understand the reference behind Clan Nutsy.

"Dude, that math test was freakin' clan nutsys!"

"I don't think you should come over right now, my parents are going through a divorce and it's been clan nutsys over here"
