::sigh:: I really wish people would stop making fun of that.

You know how sometimes, people have really specific triggers no one could predict? (Like, for example, impertinence's calculus trigger that she explained in heartbreaking detail?)

If you were close friends with someone like that, and you knew about their trigger, wouldn't you warn for it, even if it didn't make sense to people who don't know your friend? It doesn't mean it's a "thing," or something oversensitive people are demanding because slippery slope. It means one friend was sensitive to the needs of another friend in a more public forum than usual. That's all. Seriously.
