I was literally thinking about this very subject and clicked on 'Off Topic' to start one up.
I understand that there seems to be a kink for it in certain Anime circles which is cool, I don't believe in kink shaming, but the varying quality of the composure on various models and the length of time it's been a thing, I reckon it's run it's course. For me, I think Belle Delphine probably nailed it and all others after that have been a pale imitation (obviously personal thought)
Going down the /RealAhegao/ subreddit is hilarious - seeing so many people doing it makes it look like a medical affliction.
