I first heard about it through Gabriel rockhill when he was invited in the deprogram, then i kept listening to other videos he made on the topic, i didn't read his or lusordo's books unfortunately, but I think the idea is clear enough for me (maybe)

Basically it includes every left leaning person in the west that poses as marxists (or anticapitalists) but act anticommunist and pro western, they're also revisionists replacing dialectical materialism with bourgeois science and bougeois ideologies,

The first time I noticed the usage of that term outside of Rockhill, was in an Instagram reel about China, then in a horrible red pen video that is also about China, it was so weird for me bc the usage was empty of all substance,

It feels like it's used to shame people about thinking that China is revisionist more than actually serve as a valid argument, and doesn't correlate with the actual western marxist types like zizek or varoufakis,

It quickly became synonym to Ultra-leftist or chauvinist
