What do I know is that I have not met anyone who used that term who could explain it, or most of their other very confidently-held beliefs either.
There is such a thing as "cultural Marxism", and it is not a conspiracy theory invented by the Nazis or anyone else.
Consider for example the 1981 book by academic Richard Weiner, "Cultural Marxism and Political Sociology" [0] – it discusses "cultural Marxism" as a real thing, in a positive light, and it is a real academic book, not some conspiracy theory hoax. Or similarly consider Dennis L. Dworkin's 1997 book "Cultural Marxism in Postwar Britain: History, the New Left, and the Origins of Cultural Studies" [1] – not some conspiratorial tome, it was published by Duke University Press. Or American philosopher Frederic Jameson's 2007 book "Jameson on Jameson: Conversations on Cultural Marxism" [2] – also published by Duke University Press, and not a conspiratorial work either
Cultural Marxism is a real movement in post-war Marxism and academia. To what extent it influenced movements such as BLM is a question about which reasonable people can disagree. But its existence is not a conspiracy theory.
No doubt some of the more extreme claims uninformed people have made about it do venture into the realms of conspiracy theory. But it would be wrong to assume that everyone who makes a claim like "cultural Marxism influenced BLM" is using the phrase "cultural Marxism" in such a sense. You'd have to investigate what they actually mean by it.

This might be contrasted with “postmodern Marxism” or “postmodern neo-Marxism” which is some kind of pseudointellectual epithet but is seems fundamentally incoherent. Postmodernism rejects grand narratives about society, but Marxism itself is a grand narrative (namely, that capitalist society should be framed as a class struggle between workers and capitalists).
In the other hand, I think there’s reason to believe the term “cultural Marxism” has undergone semantic shift recently. I see this quite frequently in progressive/conservative politics (another example is the term “woke”). So it may be best to either retire the term altogether or at least explicitly define it first. The cultural Marxism discussed in 60s and 70s academia is not the same thing as what the Norway terrorist was referring to in his manifesto.
Postmodern Marxism is a real thing too. See for example yet another Duke University Press book (Duke University is really into this kind of stuff for some reason) from 2001, "Re/presenting Class: Essays in Postmodern Marxism" [0]. Another more recent book is "The Condition of Digitality: A Post-Modern Marxism for the Practice of Digital Life" (University of Westminster Press, 2020) [1]
Are postmodernism and Marxism inherently contradictory? Well, "postmodernism" is a very broad and amorphous school of thought. The idea of postmodernism as opposition to "grand narratives" is due to Lyotard, and yes that idea seems rather incompatible with Marxism, at least in its classic form; but other postmodernist thinkers emphasised different ideas, whose incompatibility with Marxism is less obvious.
I also am picking up on the fact that you are obliquely referring to Jordan Peterson, who is known to use the phrases “postmodern Marxism” and “postmodern neo-Marxism”. Honestly, I've never paid him a great deal of attention – I'm neither one of his fans nor one of his haters, I'm just not that interested in him. So, I can't say whether he is using the phrase "postmodern Marxism" in the same sense as those academic books I cite do, or in a different sense.
> The cultural Marxism discussed in 60s and 70s academia is not the same thing as what the Norway terrorist was referring to in his manifesto.
I don’t know about that. Let me put it this way: the World Zionist Congress (WZC) is a real thing, an international conference that was first held in Switzerland in 1897, and it was held for the 38th time in Jerusalem in 2020. So the conference is not a conspiracy theory. But, if you go looking for them, you will find antisemites who will tell you that the WZC secretly controls the world’s banks and governments-that is a baseless conspiracy theory. However, even though we have both a real world factual discourse about the WZC and an unhinged antisemitic conspiracy theory about it, that doesn’t mean that the two discourses are using the term “World Zionist Congress” to mean fundamentally different things-no, they are both talking about the same thing. In the same way, just because Breivik talked about “Cultural Marxism”, doesn’t in itself prove he was talking about something different - he could be talking about the same thing, but making baseless/unhinged claims about it, and wrongly using those claims to justify his senseless mass murder of innocents
As a simple example, in the conspiracy, cultural Marxism is used nearly synonymously with multiculturalism. Neither of your links mention multiculturalism even once.
And, it is false that "cultural Marxism" the real world academic movement has "no relationship" with Breivik's concept of "cultural Marxism". In his manifesto, Breivik cites figures such as Antonio Gramsci, the Frankfurt School and György Lukács, who were foundational influences on that academic movement. So he is talking about the same thing. That doesn't mean his criticisms of it are sensible, nor do they in any way justify the unspeakable horror of his violence.
Imagine reading an antisemitic screed against the World Zionist Congress, which mentions its real founder and first President Theodor Herzl, and other key early figures such as Max Nordau, Abraham Salz and Samuel Pineles – but then baselessly accuses them of secretly controlling the world's governments. The baseless and irrational accusation doesn't change the identity of the targets of the accusation, it doesn't mean "the screed isn't actually attacking Theodor Herzl et al, rather it is attacking imaginary persons who by coincidence have the same names". In the same way, Breivik's claims about the academic cultural Marxist movement are ignorant and over-the-top, but that doesn't mean he isn't actually talking about them, and instead talking about something completely unrelated.
Again, the Zionist example: there are definitely criticisms of Zionism which are nothing more than baseless antisemitic conspiracy theories (e.g. "Zionist Occupation Government"). But, that doesn't mean all criticisms of it are so baseless. If you read pro-Palestinian authors, or even left-wing Jewish Israelis, you will encounter critiques of Zionism, which whether they ultimately be right or wrong, can't be dismissed on the same grounds.
You will also find claims that some people on the pro-Israel side want to erase the difference between non-antisemitic criticisms of Zionism and antisemitic criticisms of Zionism, in order to put Zionism itself beyond criticism – and I think sometimes those claims are correct. On the other hand, sometimes pro-Palestinian criticisms of Zionism do cross the line into antisemitism, and as applied to those particular cases the claim is false. Part of the problem here, is it isn't always clear where to draw the line between non-antisemitic and antisemitic criticisms of Zionism–it is a question about reasonable people can disagree. Non-antisemitic criticism of Zionism and antisemitic criticism of Zionism aren't totally disjoint, they bleed into each other at the edges.
And I think we have a similar situation with "cultural Marxism". Yes, Breivik's criticisms of it are conspiratorial nonsense – but is everyone else's? There are right-wing criticisms of it which, whether correct or incorrect, arguably aren't "conspiratorial nonsense" – see for an example, see the 2018 article by the conservative lawyer Alexander Zubatov in the Jewish magazine Tablet, "Just Because Anti-Semites Talk About ‘Cultural Marxism’ Doesn’t Mean It Isn’t Real" [0]. There are even left-wing criticisms of it – the cultural Marxist desire to switch the focus of Marxism from economic to cultural issues was (and still is) heavily criticised by orthodox Marxists who view that switch as a distraction and a mistake.
And I see two other parallels to the Zionism case: firstly, just as some Zionists arguably seek to dishonestly erase the distinction between non-antisemitic and antisemitic criticisms of Zionism, in order to put it beyond criticism – in a similar way, my own impression is that some progressives seek to erase the distinction between conspiratorial (even antisemitic) criticisms of cultural Marxism, and non-conspiratorial (even if possibly mistaken) conservative criticisms of it, in order to shut down debate.
And secondly, just as the boundary between non-antisemitic and antisemitic criticisms of Zionism is open to debate, I think the same is true for the boundary between non-conspiratorial and conspiratorial criticisms of cultural Marxism. In my own mind, Zubatov is clearly on the "could well be wrong but not conspiratorial" side of that line, and Breivik is definitely on the "conspiratorial" side of the line – but I'm less clear about where to put something like the Heritage Foundation's criticisms of it. [1] And that's the core problem with your idea that we consider conspiratorial criticisms and non-conspiratorial criticisms of "cultural Marxism" to be talking about two completely unrelated things – it assumes a clearcut boundary between the two which may not actually exist. I think it makes more sense to speak of a continuum of criticisms of the one thing (ranging from the reasonable to the ludicrous, with the boundary between the two being debatable) rather than claiming the reasonable criticisms and the ludicrous criticisms are criticising two completely different things.

"Cultural Marxism conspiracy theory" is about claiming that said post-war academic movement is a "Jewish plot". Yes, that's an antisemitic conspiracy theory. But stating that the academic movement exists, and discussing to what degree its ideas influenced contemporary social movements such as BLM, is not a conspiracy theory, and not per se antisemitic.
I think what is happening here, is some people are motivated to ignore the difference between what is a reasonable argument ("to what degree was a contemporary social movement influenced by a contemporary academic theory") and what is an unreasonable one ("it's a Jewish plot"), because they want to shut down that reasonable argument

Good stuff.
"The tradition of Marxist cultural analysis has also been referred to as "cultural Marxism", and "Marxist cultural theory", in reference to Marxist ideas about culture."
https://en.m.wikipedia.org/wiki/Marxist_cultural_analysis
It is >also< a name used by people who believe in a conspiracy theory about egalitarian politics.
The large crowd was easily swayed into going along with stuff like this and its just taken a while to get rolled back because we realized it went too far.
