Extrava-ginzo 

An over-the-top Italian wedding. See, e.g. the opening scene of The Godfather.

I have to go to Giuseppe's wedding tomorrow. It's going to be a real extrava-ginzo

Extravaganzology 

Ancient Greek: -λογία

Medieval Latin: -logia

French: -logie

-logy: A subject of study or interest; A branch of knowledge; A science.

Extravaganzology:
The study of all things beyond the bounds of reason; the study of all things excessive; the study of unrestrained resource expenditures.

The Joker’s maniacal extravaganzology only served to sharpen his chaotic genius, dabbling in everything from chemistry to mechanical engineering.
