It's not even just the pooner shit, either, though that does obviously play a part. She just has a smile that is comparable to Chris Chan's smile, to me at least. It's something about her sped smile and the kind of vacant, out-of-touch look in her eyes. You can see it in her old cosplay pictures before she started LARPing as a man, too.
I can't remember what page it was on, but there's a video of her alone at a restaurant eating sushi. Her mannerisms and behavior are just painfully autistic. She's also blessed with naturally long, dark eyelashes. There certainly are men who have long, dark eyelashes, but it doesn't make them look feminine because they're men and their overall bone structure and stature makes that pretty clear.
