Why do Japanese people use the kanji "草" (grass) to mean laughter?

Also, I’ve noticed a lot of people using the 🥺 emoji...
Why is that so common?

It looks like something a pathetic little anime girl would use.

Is it meant to be cute or ironic or... both?
I don’t get it, but I keep seeing it everywhere.
