Crazyism 

When someone is crazy and they are so crazy that they don't even realise it.

I suffer from crazyism.

Acting crazy, hyper, stupid, etc. usually in the company of close friends at a boring place.
Degrees of word:
crazy-adj.
crazyish-adj.
crazyishness-adv.
crazyishnessly-adv.
crazyishnesslying-verb

So we were at the retreat and had nothing to do so we stood around crazyishnesslying all night.
