Can't speak from post-situationism, specifically, but me thinks you've hit squarely on the head of the matter here.
Isn't memetic representation, as memetic reference, per se. Nor subculture, in any indefinite article sense.
Rather, this is 1980s Usian high school clique culture, wherein the regulars at a certain table in the lunchroom, who identified as the unpopular kids, the kids that got stuffed into lockers and mistreated by the mean girls, ascended in social status.
Starts with *original* media, movies, about "nerds" and kids playing on their computer modems being the protagonists in power fantasies. Only a shift in the principle sociotechnical imaginary of society subsequently placed those once put-upon smart kids in positions of hierarchical power in the real world.
Today, every time references of once niche interests appears in popular media, it's an affirmation that those bullied kids of two generations ago are now the ones culture caters to.
