Any overt display of wealth so staggeringly flagrant that the person in question might as well be wearing an actual garment made from actual cash money.
This guy steps out of a classy restaurant wearing high-class threads, a metric ton of gold, and a hired-for-the-night woman on one arm. The tip he laid on the valet weighed the boy's hand down, and when they bring his car around, it turns out to be a monstrous SUV
that requires it's own ZIP code.
All in all, the biggest money hat I've seen all week.
