flousy
The frivolties associated with living in the upper Eschelons
of Society.  Excessively expensive, frivolous, non-essential things--Gaudy, Ostentatious jewlery, Exotic cars, Private supersonic jets...   
Though he now poses as a charitable man, Former Microsoft CEO Bill Gates lives a life full of Flousy with his private submarine, his ridiculously automated house...

"We flying first class
Up in the sky
Poppin' champagne
Livin' the life
In the fast lane
And I wont change
For the glamorous, oh the flousy flousy" 
- Glamorous by Fergie

"Honey this flousy Valentine's dinner just emptied our bank account!"
