That's racial fetishes. Asian women fetishizing on white guys.
I've seen a lot of that in porn, it's usually men's perspective, but here it's women's. If you wanna see what i mean "blacked" or it's opposite "bleached" are the keyword for black/white racial fetishes.
To me this meme and everything like this is to far and an unhealthy way of fetishizing over a race. It's not just liking a race wich is fine, but putting it above others.
