You can get a good sense of what's happening in pop culture by perusing the many T-shirt shops located at the Jersey Shore.  Here are some observations after a trip to Seaside Heights over the 4th of July holiday.

It should come as no surprise that President Trump, and politics in general, were popular subjects in many T-shirt shops.  You can find pro-Trump shirts, anti-Trump shirts, and even a "Bernie 2020" shirt in at least 1 shop.

Drug references, like Backwoods, remain popular.  The same goes for Rick & Morty and fake "Supreme" logo shirts.
