This is a link to a page with a working definition for BwO which I found to be helpful in understanding the concept. It seems like D&G are interested in a sort of “flow permanence” or “process logic” which jives with NLP, but they express it through particularly idiosyncratic language. There are, of course, other facets to the concept, and the author of the page goes out of their way to make a point that this definition applies more to Anti-Oedipus than any of the other areas that the concept appears, and I found it to be useful nevertheless.
Additionally this is a concept linked to the BwO (in my mind) which I came across while looking into the BwO. It feeds into an idea I have been developing internally regarding information throughput in social systems.
