Some great ones already mentioned. So here's another three, not in any particular order:
Fake Westernized ethnic foods: unauthentic fare that's unrecognizable in the namesake's homeland. Fusion food is for those who can't cook properly.
Las Vegas and Dubai: the biggest, grandest, flashiest of everything, but lacks real soul and character. The epicentres of tasteless.
Excessively large external hard drives: it's all the rage, everyone has to have at least 1TB. You save your life's pictorial history in it, then it dies and erases your past.
