think there's some kind of strand, in terms of their emotional resonance, running through south park, GTA, eminem, kanye and trump. something about the way the part of the attraction with all of them was the shock value, willingly offensive. and actually with the exception of kanye, the aesthetic ugliness of them all (i guess GTA is debatable with the later games). quite a range of mediums but working in the same way on some level, though obviously beyond this common strand they're all doing multiple other things at the same time.
also all american things that gained traction in the UK to various extents, but i do think like all this stuff, we do experience them as imports and therefore they are a bit more distanced than they are for americans
