The WWF had a large, athletic, tough woman named after an Asian country (Chyna).
So of course WCW decided to (I guess) one-up them by naming their wrestler “Asya”.
Because Asia is bigger because it’s the continent that contains China.
Get it? Chyna/Chyna, Asya/Asia?
Oh, that WCW was so darn clever…
The difference is that Chyna had a personality and could work a match, unlike the completely useless Asya.
