Mockstalgia 

Any revisit of a thing, be it music, art or otherwise, that tries to evoke nostalgia but rings hollow like it's also mocking said thing. A thinly veiled inside joke

Bands like Wet Leg callback like 90's cool but are really mockstalgia because they don't believe it... they're goofing on it
