Yep!

I have PTSD and I don’t get too upset about it because I know the joke will die out, but it’s annoying. It’s similar to someone saying they have OCD because they like their desk organized— it spreads misunderstanding and is just generally dumb trash.

It feels worth saying that it has valid applications outside of PTSD also, most of the time a trigger is just something that brings out an unhealthy behavior or unpleasant feelings.

You could say going to bar is a trigger for a recovering alcoholic, because it brings up the desire to relapse. With misophonia, sounds that the person has trouble tolerating are called triggers. But you wouldn’t say that something unpleasant is “triggering” unless it brings up something specifically related to your mental health.
