Crazy Coconut 

Used to describe a female during PMS when she is acting completely irrational and crazy. A perfectly sane girl can turn into an absolute psychopath who will randomly cry uncontrollably for reasons they do not even know but of course it will be the guys fault. When females are experiencing this crazy coconut syndrome they should be avoided at all cost for at least 3-4 days, do not communicate with them through any medium as they might unleash on you at any time. There is no known cure for this crazy coconut syndrome, yet some scholars maintain that chocolate, warm drinks, hot water bottles, bunches of flowers and saying lies like "yes your right, yes it my fault, its ok that your like this" seems to calm the beasts.

Shes being an absolute crazy coconut, stay the hell away from her.

I don't claim to know what Mel thinks, and i don't really care. What is pretty clear is that the man is crazy in the coconut.
