Fake opulence. Example: donald trump. Gold gilded everything in extreme excess. Properties that look like a "B" movie cheesy bordello. Trying to be 'hip, flashy cool, in'. And looking ultra cringe trying.

Non-political example: Big ass, loud, overly decked-out truck. Raised up adds 10,000 points, diesel adds 1 million points.

People who are actually classy don't have to try. And being classy was never their goal. Trashy takes a lot of effort.
