I still see vestiges of "le epic bacon" out there but it's mostly confined to aging :grillman: types and some :up-yours-woke-moralists: cultists and a few contrarian carninist edgelords that want to "trigger the vegans." Yes I know all of the above have a lot of overlap.
I think it came from "we live in a society where XYZ thing happens" and then reactionaries cut off the last part to try to mock it, and then it got reappropriated through irony idk
