I think he is talking about her eyes .
They could seem kind of funny looking to some people .
The way are a little too big . Bulge out a little.
Like that actress in the Fallout TV Series .
I like it it is kind of Hot .
The eyes wide kind of thing .
A bit like some kind of Ahegao. Its hard to explain.
Just a guess though.
There are shittons of instances of her talking, specially on her stories. I'm sure you can find many videos of her talking on tiktok. She is also not AI, she's been making videos way before AI was any good at making videos.
