Jubilatory 

When you're overjoyed but too tired to remember how to use the word jubilant.

I feel all jubilatory (if that's even a word) and excited and like i've completed something except mostly I've done jack shit.

Jubilator 

The master of all Jub-like creatures; One who jubs; one who hates definitions that uses the main root of the word its defining in the definition.

The jubilator was the pimp of all the mini-jubs.
