Specialized in group jargon and acronyms show up in a lot of places.

I'm not criticizing it for being jargon. A word like "steelmanning" is also jargon. But it's not in the same category emotional distancing as "AMSS".

There are also times where intellectual distance is useful. In academia you don't want emotions to interfere with your reasoning. In the case of PUA, the language allows suppression of approach anxiety. Intellectual distance allows a PUA to run his routine without interferes of his emotions. At the same time prevents real emotional connection to see interactions with the goal of maximizing the amount of k-close, n-closes and f-closes.
