Absolutely. I've seen a psychologist commenting on Twitter (possibly Dr P, a clinical psychologist) about how a state of euphoria is linked to psychological problems, such as those listed in a comment above.
It's a kind of double red flag: mental health concerns and the possibility of autogynophilia. The fact that it's used nefariously as a code word amongst autogynophiles, when hiding in plain sight, is key in how it will no doubt play out more widely in the public discourse soon, now that people are paying closer attention. There will be a lot of evidence/receipts of autogynophiles dropping such words in to general conversations and interviews. Obviously there are plenty of other words and phrases that carry meaning related to arousal.
For clarity, I'm not comparing autogynophilia to paedophilia (as the former isn't illegal, presumably because those who are involved - without consent - in the person's fantasy aren't underage) but it's telling how the public only really acknowledges the hiding in plain sight calling signs in hindsight e.g. looking back on footage of Jimmy Savile and how he dropped clues in so many times, either by a particular phrase that he used or by a certain look that he gave the camera when saying something that would otherwise be innocent. As has been pointed out many times on this board, the thrill of getting away with dropping in clues (presumably knowing that some people will spot them and - in the case of autogynophilia - risk being called bigoted or being arrested by police for "transphobia" if they try and call them out) is part of the arousal/euphoria.
I was trying to find a thread I had bookmarked on X by a transwoman who talked about how much of a turn-on it was to be in ladies' toilets and have women speak kindly to them. In this thread, the transwoman was mocking the women for being so dumb (i.e. for being kind and not realising what was happening). As I don't have a paid X account, I can't search my bookmarks but here's a longer video from MaryCate where a she reads out words from transwomen on the euphoria/arousal subject (sensitivity warning again):

Her pinned tweet has the whole collection of videos that she's done, now with a handy intro by topic.
Again, I should reiterate, I'm not saying that anyone has deliberately and nefariously used the words "euphoria" or "daily affirmation" in this thread.
