I've heard advocates of trigger warnings share their lived experience by talking about what "triggered" them, using that word specifically.

The word is used in the context of PTSD. e.g. "hearing fireworks triggered flashbacks from the war"

More generally, a "trigger warning" is a "content advisory warning" by another name.

There's a big difference between describing one's own experience and labeling others.
