As a counterpoint to the previous post, clearly the layers on layers remix culture of the 90s and naughties has provided something new. My personal pet example is the Charlie Don't Surf T-shirt. It combines a picture of the serial killer Charles Manson with the Apocalypse Now movie quote. Axl Rose used to wear it on tour.
To get the full effect of that T-shirt you really need to be up on your pop culture: You need to recognize Manson and know his name. You need to recognize the movie quote. And then you need to ground both of these quotes on a drug fuelled early 70s pop culture and recognize the wild disconnect in the two references.
A lot to ask of drunk rock fans.
